Steve,

I have tried one a couple of time on the artificial putting green in my Winter Golf School.  

Positives:
Extremely stable.  The putter is hard to swing off line, and just feels solid.  This putter is hard to miss hit, and great on short putts.

Negatives:
Weston has extremely fast greens, which this putter wouldn't lend it self well to with my stroke dynamics.  I have a up tempo stroke and prefer a lighter putter which helps with my tendency to smash putts.  

Overall

If you have a smooth tempo and like the look of the putter it is the best counter balanced option out there.  

Hope that helps.   

I also tried one at the local shop in Myrtle Beach. I tried one with a 38 inch shaft as I like to stand a little more upright. When I tried it on their indoor putting green, I set up a ball between the holes and putt to it to get a feel for the ability to hit a good line. I think they slope most of the holes to track the ball in so as to sell more putters.

The good news is that I really did like the balance and the weight. It promotes a smooth back and forth stroke which is critical for me to keep the putter head on line.

Unfortunately, I could not afford the price tag, so I will have to wait as I am currently saving up for my new 913 Hybrid that I plan on getting this summer.
