Joe,
What size arrow are you using??? I have the problem you mention with my old poltruded carbons but not with my ICS type arrows....I can literally shake my bow and they don' t fall into the slots I cut... Put about a 400 yard bellycrawl/stalk on a turkey yesterday (unsuccessfully I might add ) with an arrow nocked and it never left the center of the bisquit.....I' ve probably put nearly 1000 arrows through mine now and have yet to have the problem you mentioned....Do you have a way to post a pic??? I would like to look at your rest because I' m curious as to why yours isn' t working.......

After thinking about this I might add that mine is a full biscuit (i.e. not trimmed in the back)...maybe this is it.......I will chat with my buddy and see how his is working since his is trimmed in the back and I modified it exactly like mine....I' ll let you know.....
