I also shoot helical with a bisquit and have NO PROBLEMS AT ALL. I use AAE vanes and AAE glue and yes its always good to put a drop at the end of the fletch.

I can honestly say that the bisquit is the best rest i have ever owned. I have had a couple including the NAP drop away (which broke this year thats why i went to the bisquit) I really like being in a tree stand shooting down and not having to worry about your arrow falling off your rest. Its quiet and seems to be very durable. Freezing problems??? dont know yet but they make the spray for it.
