RE: what's up with my Wisker Biscuit??
From the look of it, it appears your Biscuit is not set up right. Looks like the arrow is slamming into the lower left part of the rest. Are your vanes showing damage? What speed are you shooting? Which way is your cock vane/fletching facing? (should be up)
I would make sure your center shot is correct as well as setting the nock at 90deg. to the string. Also check your tiller it helps to start out with an even tiller.
Need more information on your set up to help more but you have something not right there.
