Twist (or untwist) the string but you'll need a press to do it. You can do it by passing strands around the peep but that's dicey under full tension for breaking a strand.
I have a portable press, and planned to make the changes with the tension off the string. First loosen the string, make an adjustment, then put the tension back on and check it.
do you shoot with a loop and release?? if so, just follow your peep with your loop.
Good idea, but I'm one of those crazy finger-shooter guys, so I'm willing to play with it for a while to get it right. Just needed to know how to proceed
