Guys, I've got an old Bear round wheel compound that I've had for about 10 years. It is a 65# 30" draw. I've tightened the limbs down as far as they will go, but the new bow scale I have shows only 59#. I'm not sure how else to increase the draw weight. The wheels have the cable in the middle slot. Are the other two slots just for changing the draw length, or will they also affect the poundage? I'm shooting 2413's 31" long with 125gr field points.
