it seemed to shorten up my draw length a good amount. i have to lean my head forward to reach my kisser button now. i'm going to have to go out and get the 30inch module. but in the shots i took, it doesn't seem to be wearing any. i put wax on the cable and none of it came off. i called up my pro shop and asked what they did to it and he said he just moved the stop to make it a half and inch to an inch longer draw length because they didn't have any 30inch modules in. he also said that will take a couple weeks to get in so i need to find a place to get it. also i brought up to him the wearing on the cable and he said that all bows with cams similar to that do it. but they are a new dealer with bowtech so they are not familar with it i guess. i don't know, it doesn't seem normal to me.
