Last year I picked up a Pro Thunderbird, was very impressed, and bagged it for several months. Great disc! I replaced it with a fresh GStar Thundy when it started losing stability. Nothing wrong with it, but at that point it was starting to overlap with my most stable Valk. Cycling Pro Thunderbirds would make a lot of sense, though. I could see myself doing that if I ever improve my form enough so that I don't have to lean on Valks for distance as much.
