I haver just played the weekend in 45 degrees and without knowing what ball I was using these are the differences between the test balls and my usual Pro V 1

Chipping.................................Found very little difference

Putting ...................................Found that in my opinion the ball came off the putter at a faster speed so no need to thump putts

Spin off the tee.......................I was no aware of any difference

Approach Shots.....................I think that my Pro V1 stopped better but that could have been the wet and windy conditions

Longer Shots.........................I think the test ball was longer off the tee and with irons and rescue club

Feel.......................................The fell on both my usual Pro V1 and the test ball was very similar

What do I prefer....................This time of year i think i prefer the test ball maybe in the summer i think the Pro V1 

It will be interesting to read other views

Cheers
