According to the owners manual on the Patriot single, I can get a module #.5 and get 65% letoff at 30". If I'm at 80% @ 30" with a # module, would I also gain a 1/2" of draw length by going with the .5 module or does it only change the letoff? The reason I ask is that I normally shoot a 31" draw length and I'm having to shoot a really long loop to get my anchor point where I want it. If I could gain just a 1/2" of draw length I would be just a little more happy.
