I have a Drenalin LD which I have recently changed the strings and replaced the cam with a longer draw length cam. I have the axle to axle back to spec and the timing seems bang on, but somewhere along the way I have dropped from 69 lbs. to 63 lbs. and can't seem to get it back. I replaced the original strings with new winners choice, and went from a 29" cam to a 30.5" cam. Any suggestions on what may be astray. If I was to twist the strings to bring my axle to axle measurement under the factory spec, would list increase my draw weight. Thanks.
