I am sure this has been explained many times before but please indulge me. I really want to put a Schaffer dropaway rest on my Allegiance. Reason being I had a Schaffer before and loved it, but used it on my one cam bow. Lets say I put on the Schaffer and tie the cord to my bottom cable. Like most, I always try to time the dropaway so its at the full up postion just before full draw.......usually 1" or less. Questions:

How will this affect the timing on my binary cam bow?
If there are any effects, what can I do to restore the timing of the binary cams?

If it does indeed affect letoff that doesn't bother me, as long as the letoff isn't a huge amount. Accuracy is above all in my quest. Just wondering what effects and if any, exactly what cures.
