bald

In case you did not know it, using vanes you added as high as 40 grns to the nock end of your shaft. Doing so has reduced the spine of your shaft and might have thrown the FOC out of balance.

Dump those vanes. Feathers are better and faster. I tried vanes last season. My bh's were flying horribly. I shoot 5" feathers and get terrific flight.
