You have to make sure you have proper cam rotation. you will see 2 small holes in the cam, these should run parrlel to the string. The Q2XL dosn't have a radical dropoff like some other single cams, it also is not a 80% letoff bow. I would not file the cam or alter the bow in any form to try & change the way the bow was designed to be shot. If you shoot a Q2XL & a Conquest you will notice the Conquest will have a much more rapid breakover into the valley than the Q2XL. I really like the way the Q2XL draws & shoots, in my opinion it is about perfect but some do not like this & want to really feel that letoff (or perception) when it rolls over. If I am guessing right this is what you may be talking about.
