if I use the straight clamp on my bitz and I can't glue my blazers on the whole length fi I go offset as far as possible.
So I changed it to less offset and now they are glued all the base of the vane.
I still am thinking of buying the helical clampto seeif it works, I think even with short vanes as the blazers it'll help your arrow fly better.

Or I could ask Bohning to make blazers with a larger base.....
