I kinda figured that out on my own, but thanks. This is likely going to be a good learning experience. When I got the new string/cables in, I thought that, since I already have a bow press, I would take a shot at installing them myself. Took some very careful measurements off the old string. But, apparently, I should have been paying more attention to the cables. Old setup was perfectly tuned. I was a little taken aback when the bow, after changing out the string/cables, shot about 8" higher than before. Broadheads shot low and left. But after spending most of the day yesterday tuning, I got them shooting the same. I think you are right about the back wall. I'm getting some interesting vertical dispersion - not bad - an inch or so. Thought it was just me. But with the shorter DL, probably getting into the back wall a little more than before. I'm heading out to the shop right now to do a little cable adjustment . . .
