RE: So I'm getting a new bow...
Not that I know much, but I was thinking the same thing in regards to the spine as I've heard a couple other guys needing to up their spine to get better tunability. The CAMS are HARSH, you should've expected a pretty harsh draw with a short valley with that bow, that's where all that speed is coming from. Unfortunately, you're not the first guy I know who's been disappointed with this bow, on line or in person, I know a few both places that just weren't as happy with it as they were hoping. Granted the one knucklehead went from shooting a60# matthews to trying to shoot a 70# 82nd, so either way he was probably not prepared for the BIG CHANGE in draw, speed, and forgiveness. If it's not the shooter or the tune, you might still be able to re-coup something by putting in out F/T for a Katera on AT.com classifieds or someplace. I know there ARE guys looking for them, wanting to change things up a bit. You might find the right one and be good to go on a trade for what you're looking for.
Good Luck, either way!!!
