I started with the Aviar. Then switched to Pro Ryno's which I have really liked and feel pretty good about. However, I just picked up a couple of super soft Wizards (with the Stumptown Stamps) that I think might be replacing the Ryno as the go-to-putter. I haven't had a chance to really practice with them yet. Should have a good feel for them in a week or so
I also will sometimes use a blowfly when I need my disc to stop on contact. However, I have used it more as an approach then a putt disc, I seem to have more control when I can put spin on it.
