just wanted to add that i build the arrows myself and the blades of the B/H's line up perfectly with the vanes i know that could cause this to happen,but not the problem this time.i am just wondering if because the shafts are so small the mabye a B/H of this size is just to big. a friend of mine is shooting the same set up except he uses some open on impact B/H's, and he has not had this problem.I know when i had the bow set up at my local shop he used a laser to center every thing and with the pratice tips as you can see in the picture @ 30 yards it's dead on

Oh if it matters or might help i shoot left handed
