OK, so I have the limbs cranked all the way down and am still 2lbs. short of peak weight (70). Any suggestions on how I might get those last two, or possibly more pounds out of the bow? Is it a simple matter of cable twisting? Bow is basically set up from factory, all I have done is sync cams to hit stops simultaneously. This thing shoots lights out and I am quite pleased with it, but I would like to get as much as I can out of it. What do you say?
