Great Putter for Drives/Approaches

I love this disc. It feels smooth and has a pretty dependable line. I don't generally use my Keystone for putting, but that could just be due to the plastic more than anything else. I care much more about the feel and grip of the plastic than about the stability and glide when it comes to putting. I generally find that my release just isn't consistent enough with this disc for me to use it on a typical putt. 

What I do use this disc for is basically any shot from 40-150 feet. I feel as automatic as I can be throwing this with a control grip backhand, and the rim feels slightly deeper than many putters, which enables me to also like it for forehand approaches. If I have a short downhill drive, I will typically pull this one out as well.

The Keystone is so close to being one of the best putting putters on the market. I love the glide for longer shots which allows me to extend my putting range by a few feet. But the rim is just too deep. I can't get a clean release out of it because of this. I also never use it as a throwing putter just because it's way too understable, but that might just be the retro plastic.

Any put over 40ft and I'm going for this. Any put in the wind and I'm at least thinking about going to it.
