Well I'm still confused. I was hoping for a better response. Right now it is 1 for and 1 against.
As for using my Muzzys, they work ok and they are bad to the bone. I shoot them on Beman ICS Hunter 400 carbon arrows with a Mathews Ultra-Max with a Muzzy ZE arrow rest. I just don't feel confident when shooting over 20 yards with them. I will only shoot 30 yards max at game, but 10 yards makes a big difference. I have aligned the blades with the fletching and that has helped but I was just looking for something better. If I miss, I would sooner it be from human error than arrow flight.
