i'm not sure who you talked to, but those spec's are +/- 1/4". that comes from about as close to the top as you can get. mine likes 33 1/8 ata. i'm not sure about bh since i took the grip off. i've got a bit over 7" because of that.

'exact' makes no sense whatsoever because that would mean all limbs are identical, and that's just not the case. if you've got the correct rockers, everything else on your bow is machined so that leaves the limbs. i don't think they'll charge you to fix it. see what bowtechshooter says because that sounds a little fishy. i know that bow will work with different string/cable length combo's, so when you get 72# and your correct drawlength, and the cam is timed, you're home.
