im using the NAP 360 right now which is bascially the hostage.. I thought about getting a biscuit, but again shoot error will throw that off more than on the hostage or NAP 360. The only thing I hate about the 360 is that the bottom peice of the rest doesnt exact sit flush with the arrow. I believe my brushes might be worn also on that model.

But from what I can tell, its super easy to tune and doesnt effect arrow flight any!
