Wraith - my tiny baby hands seem to have an easier time gripping the Wraith rather than the Destroyer
Harp - I was all Innova and Discmania for several years there. I always felt they lacked in the OS glide-less putter. The Harp seemed to be the disc I've been looking for. It's in between a Gator and Zone for me. Not nearly as fast as a Gator, and as OS as a Zone. Just the right amount of both.
Bard - I tried one and I really like it. Basically feels like a OS Roc3 to me. I basically took out my most stable Roc ('01 remake that I always feared that I'd lose) and the Gator because of this disc. Trusty OS flight.
Wizard - I used to putt with Wizards, but a few years ago I got a deal on some Yetis and switched. Well, now I switched back. Those PWP Wizards, with the chalky, grippy, low-profiled shoulder! Man! Those are some great putters. Also, I previously had a Nova and a Scale in the bag. But I've got a Wizard that I'm seasoning up to where I won't need a different mold for the same shot. One putter to rule them all.
