I want to be able to fletch straight, right helical and left helical. Can I use the same base for all three clamps or do I have to use straight base, right base, left base for each angle clamp? Thank you for your time. Steve

Same base will work.

All you need are different clamps. You can not beat a Bitz!

And/Or you can by a straight clamp and fletch straigh and left/right offset as hard as of a degree you wish while still maintaining fletch contact. (Depending on your fletch, it's the same result)

I offset my Blazers.
