I am currently using a whisker biscuit w/ blazer vanes. It works great, except for that it looks like i might have a clearance problem. Whats the best lowest profile vane out there? Are duravanes any good?

I like the Bohning X-Vanes or the Bohning Killer Vanes. Very nice fletchings.

What he said. I use the 4" x vanes in low profile for certain arrows and they are rugged. They are the same material as the blazers so you know they won't wrinkle through a biscuit.
