RE: Dropping DW
Only thing you have to worry about Jeff is holding weight. I know I shoot my best shots with a bow at 16-17lbs of holding weight because this holding weight forces me to engage tension in my back to hold the shot, yet isn't so much as to fatigue me. You would need roughly 69% letoff to get this holding weight out of 55lbs. 69% letoff on a binary like your Airborne is going to make the valley even smaller than the 80% they come setup at from the factory.........lol.
