Mike, thanks for the clarification on the draw module / cam module. I kind of thought that's what you meant.
From what I am reading, I guess there is no "one best setting" for draw length or cam stop on this cam, and that I'll just have to play with it? I'd really like to get close to that 80% let off.
I will try to take pictures of the cam at the 27.75" setting as described above, tomorrow. The ya'll can see how the string sets on the module and advise. I certainly apprectiate all the help.
