I have ez fletch, and bitzen, and the bitzen is good if you do only one type of fletch. I shoot 2 different traditionals, and 2 different compounds. If you have to constantly adjust the bitzen, its no fun. Also can be difficult to get a real good helical. The marks on the bitzen is no good either. I even called the shop that casts them, and he even said, you got to experiment.

I would go with jo-jan. You can put a nice feather helical on with that.
