RE: Adjustable Let Off
Without the pic, I think you are referring to the different posts on the cam to relocate the stgring. These are used for 1/2" drawlength positions. 1" changes are accomplished with module changes. And if I am right to change the let-off percentage you have to get different modules. Parker makes modules for 80% (standard) and 65%. If you can't find one then many of their bows use the same modules as Pearson bows.
