I have a bitz, and don't like it. I have a hard time getting a real nice helical with it. I seem to be able to get a better helical with the jojan. Also the marks on the bitz is a pain.

If you only fletch of one bow or one type of fletch than the bitz is ok, just keep it setup like that. But I shoot 3 traditionals with LH helical, and shoot another compound with a shoot thru (slight offset), and another compound I like to shoot hard RH Helical. Matching up your current fletch everytime is tough when doing one fletch repair.
