Bob, Im no help on the setup, but I still say try a Fury and youll never look back. Ill have a 26 in a couple months that I want to try on my PIV / 200HO at sea level, I dont think it would run it at altitude. If you still have not tried one by then I could lend you that to try. Like the recommendations on BBC, I think you should try a 25 pitch Fury, either the 25 or 26 will be the one. Mike
