Thanks Arthur. I've just not seen the rest that you mention in person, but it looks like it would allw the arrow to fall off the rest to the left fairly easily. It's cheap enough, I really can't loose. I'm already shooting 4" feathers and will continue to regardless of the rest that I select. I have uninocks, so I can adjust the fletching to what ever position is optimal.
I'm curious about the cock feather up on a wisker biscuit. What does it matter since the biscuit contacts the full length of the shaft?
