Whiskerbiscuit is fine as long as u have very good consistant form. Any torqe or xtra movement u introduce during the shot will amplify because of the contact along the entire length of the arrow shaft.
The bowmadness XL has a shorter brace height than the XS which calls for a stab. The XSseems to hold well wo a stab but I always opt for a stab for all my compound bows.
Dont forget about the Trophy taker fall away as it is a simple but very sturdy very accurate arrow rest. JMO
