I use them for everything. I have them on my ACC's for hunting and 3D. I also fletched them for my 3D arrows. Mind you tho, we cannot shoot Hunter Class with them which is ridiculous tho I've never shot HC.

I wouldn't have quams with using feathers either.

I use a straight clamp with my Bitz and offset them right, offset them hard enough to still allow fletch contact both front and back. Experiment with it on a dry run.
