I bought some Beman 340 Hunter Elites and some Carbon Express Terminators but just can't seem to get away from the alums. I really like xx78's and even 75's. I'm still trying to convince myself to go carbon. We'll see. Whatever shaft, most likely 100 gr. Spitfires although I'm planning on getting some Muzzy's. Anybody have any input on 3 blades vs. 4 blades?
