I just got some with the red number as well. Living in Ohio, was lucky enough to have a few days warm enough. They respond a lot like NXT Tour or Velocity with a little different feel. I really like them.

I received a sleeve on Sat. 10/26 - Black # with Test stamped on one side.  I don't remember what ball I had listed in my profile but, since this Spring I've been using the  2013 version of the bstone E-6 & E-5 balls. 

So far I've done a putting & chipping test, using the E-5, E-6 & the 'Test' ball and have played one round. The 'Test' ball felt as soft as the E-6 off of the putter & wedges but had more spin when chipping. Overall feel was better then the E-5 ball. On the course I liked the overall performance of the 'Test' ball, over the E-5 but thought the E-6 was very similar.

On the day I received the sleeve of test balls, I had ordered 2 dozen of the NXT Tour S balls. I just received those in the mail the other day. So, I need to do further testing, comparing the "Test" ball to the NXT Tour S ball, 

Thanks to Team Titleist for including me in their Beta testing. 

All I know is if & when this Prototype ball is released for sale on the retail market I'm buying it! Until then I''ll use the NXT Tour S balls. I liked them more then the ball [e-6] I've been mostly using this year. 

Great job Titleist!

I got mine last week, I can tell mine are not ProV's, look more like NXT's.  I play'd with them yesterday, pretty consistant ball flight, and seemed to climb a bit higer than my usual ball, and certainly sat quickly and softly too...overall, I'd buy the darn'd things if I knew what they were...drives were about average, nothing more or less, most of the difference I saw was in the mid irons and wedges...60 degree had them up and down with slightly better performance than I'm used to, but then I may have just had a good day, so I'll try them again on Sunday...Players like me (low to mid 90's) can't really judge a ball on one round...

Mine were marked in black: Titleist 1 & <test>. They flew really far! Are we allowed to use these in tournaments and to post scores?  Not sure if they comply with Rules of Golf...

Am impressed w/this ball; Black, Titleist 1 and test.   Unfortunately, weather in PA now is not conducive to much of a test.

Wet grounds and lower temps make for poor conditions for comparison.

Got the email today from Titleist asking for my opinions of this "test" ball but have only played ONCE!

Balls came last week and email today.....my reply will not signify very much info of any value.

Hope that Titleist will advise us what this test ball becomes, if anything.

as far as i can find they can be used in toury play  under append. 3 as long as they not any different in size, shape, weight ECT.

I got Black “TEST” # 1 and I play the Titleist NXT Tour ball. I have played the test ball and my ball (NXT Tour) side by side, it takes a little time and you do find yourself explaining why you are playing two balls, but everyone seemed cool with it after I told them it was an official Titleist test program. Oh and nobody wanted to play through! I measured the drive distances and calculated in distances off line. My average drive distance with the “Test” ball was 21 yards additional distance, the “Test” ball also was easier to spin to a short stop on the green, it had nice control. But it also showed wear after only playing two holes and was what I would call well used with some rough spots and fuzz after 18 holes. For tournament play this would be the ball for me and for daily recreational play that would depend on price point. And back to the golf course and all the other players who watched me play, after I showed them my math and with them seeing me play it is going to be a popular ball.

If they are test balls, you cannot use them in Competition.

I usually play the NXT line and Wilson 50 Elite during the colder months. The Wilson 50 Elite has been a solid winter golf ball for me. Can't wait to try them out and see how they perform

mine were marked in black also...test 1......not much difference in distance...but they just have a great feel. I actually play srxn Q-stars...this test ball was great...especialy around the green..much more control...putts seemed to be more true, and chipping was much more controlled. Even holed out a 15 yard greenside chip that flew about 11 yards and rolled right in. I had 2 upa nd down from bunkers, and my bunker paly is horrible. I want to know what these are...and how much??????

I too received Titleist 1 with "test" marked on them.   They were just excellent balls flying straight, longer than normal for my swing speed and quite compressible.   I would buy them today.   I have the NXT tour S in my profile and liked the test ball better.

Similar experience here.  Tested them today and was bombing them off the tee. Didn't love them around the green but that may have been user error today!  Either way super fun process.  Love the opportunity. 

If all black markings it is a ProV1, if it has a red # it is a ProViX

I've had the same experience with my test sleeve.

I  played  with mine  for  36  holes- black  numbers.  They seemed to have more spin off the driver than the  ProV1x or  Velocity I play but  more  spin around the  green too. Great to be part of the  test  proogram!

Received received a sleeve of "test" balls.   Seemed similar to NXT S, but much longer with hybrids. 

I received a sleeve also.  Would like to know what they are.  They went straighter and farther for me.   B'stone E-6 is in my profile.  Played with them in 40 -  45 degree weather and saw improvement.  I would buy them if I knew what they are.  Thanks for the opportunity.

i guess a velocity or nxt...they have very little spin and land on green with a thud and don't move

I also received a sleeve of test balls and absolutely loved them. Took the feedback survey and I am hoping to obtain more of them and also find out what type of ball it is. Very curious indeed!

I received a sleeve as well, played with them this week. I would compare the ones I received to the NXT which is my ball of choice. The balls with test on the side certainly raised some eyerbrows in my group when I pulled them out.

How did the test balls perform for you? Did you see any difference? I know I did and my foursome also noticed that I was hitting the ball 20 yards longer on most shots.

Kathy my young friend hit it and it went 305 ,,hahaha answer YES it will go and it also will stop on a dime. I want some.

I got the sleeve of balls and played them last weekend. It is a shame we never know what they are because I LOVE these balls.  Longer and firmer off the tee, great check up ability on pitch shots and only had 28 putts in the first round I played with them.  Took a bit to get used to the firmness compared to the NXT ToursS but once I did they were awesome. Seems every part of the game was better.  I had to select shorter irons on approach as the shots were sailing long on the fairway shots.

Happy to say I was  received a sleeve as well. Black numbers. I usually play NXT Tour balls. I played 9 with the prototype balls today. They were amazing. No way they are legal. I was 15 yards father with the Prototype with the driver, about 10 with long irons. With short irons, the ball flew higher and spun more. And the ball went straighte with all my clubs, especially my driver. I tend to push the ball with my driver but this ball just seemed to want to stay straight and draw! It felt much softer than the NXT Tour, too. Loved the ball and hope one day it comes out. Truly an amazing experience playing with the prototype.

Also just received a test sleeve.... Will try them out tomorrow.

Anyone want to take a guess at the compression ratings for these balls?

I love the Duo & was hoping Titleist would put out something similar.

I would say 60

Anybody receive a test version of the new PROV1X?  If so, were you able to see any noticable changes vs. the 2013 model?

i received also a sleeve of 3 white test balls two weeks ago. Whatever they are I want them! I am more of a line drive hitter (on purpose with woods) and my irons get sufficient height but not impressively so. With these, they climb fast and stayed high for a long time. The result has been longer tee shots, and softer landings with my irons. My irons may be slightly shorter but I would trade that distance for the consistancy of the height, aim, and soft landings any day!

I have the "Velocity" balls in my profile, but these are definitely not them. I always thought that a golf ball was a golf ball was a golf ball. Not anymore; I would replace my Velocity's with these in a heartbeat. I would also clean out from my bag all my cally balls that I had been using.

Titleist; Please tell me what they were and where I can get them. If you need warehouse space, send me the excess!! :)

Not sure gonna try them tomorrow but they look shinny-ier than the ProV1
