No, none.....I use the Bitz at the shop I work at, and honestly it works just as well. I hear an aweful lot of "Bitzenburger this, and Bitzenburger that....." Yes, the Bitz is a great jig, no question.....I simply CANNOT see spending 70 bills when the grayling is less than half that and works equally as well.

I've used my Grayling for 3 years now, and fletched.......I couldn't even tell you how many arrows. Not one single issue have I had that wasn't my fault...Stupid mistake so to say.
