There are some huge threads including one updated just today. Take a look through the flatstick section and you might come up with what you are looking for.
Thread around here somewhere, plus a homepage review. I just got one, and from one round I can say that if you like a firmer feel, these putters are crazy good.
Oh, the putters...
Also- they are really really great putters for the price. If you can get your hands on one and try it out you'll be very surprised.
I think it was JB who had people test them, and the people thought they were the top of the line putters.
I saw the other thread literally seconds after I posted this. I'm thinking about getting one. At my local golf course they have them for 78 so i can get one for a little cheaper than golf smith.
