Thanks for the replies guys. Wihunter, do you have any pictures of your setup? I've seen many different setups and it seems like there's varying opinions on techniques/materials, etc. I've heard it's best to place the peg/rod about 2-3" down from the crank to best simulate the different planes that exist when pulling back a bow (location do your hand on the riser is lower than the nock point). Is this how yours is setup? I've also heard mention that these are best suited to verify/adjust draw stop timing but NOT cam synch. How does one go about adjusting/checking cam sync?
