I have had nothing but good from the Spitfire 100's. I have some 4 blade Muzzy's that I just can't get as accurate as the Spitfires & field tips. Close but still not dead on. Same with some 3 blade Theads. I have some 3 blade Satellites and Eastmans that are worse. A friend gave me a few blades that flew pretty good. One is a Nitron and I can't remeber the other but it was a Razorback or something. It was a 2 main blade with 2 bleeder blades and it rotated. I think the purpose was if it hit bone it would just spin. It was kind of odd but it flew great until I shot at a squirrel and hit a cedar tree. I think most of the blade is still buried in that tree. I am going to buy some of the Nitrons. Its a short blade with about 1 1/16" cut but it flies great. I was going to buy some G5's but heard one of the guys at the pro shop tell a customer they didn't fly good. I may have to try them as a lot of people seem to love them.
