It's my first bow. The package came with a whisker biscuit, but I see others are using a drop away rest. Is there a performance advantage? I'm so new at this that I'm going to stick with the whisker biscuit for now, while I get my feet wet, but I was curious more than anything. If anyone could explain this to me, it would be much appreciated. I'm new to all of this and trying to learn as much as possible. Thanks, guys.
