Yes, the draw stop on the top cam will change the draw approx a half inch if adjusted all the way. It will also give you 65% let off. I wanted 65% let off and bought new cams to achieve this. Just bought E4 cams, 28.5 draw instead of the E5 28 in draw that came on the bow. The valley is almost gone, and is easier to draw yet. Oh, and the cams are cheap. 60 bucks for the pair. Took about 2-3 weeks for delivery.
