Well there are a few "sticky" threads at the top of this technical forum for the tech heads. It's good stuff. If you crave more, go to archerytalk.com. Check out the "bowtuning" and "general archery information" forums and you can find just about anything your mind could dream up about bows. But beware though, some of it is opinion based, and with experience, you'll find that youprefer certain ways of doing things that suit youbetter. But all in all, this site and AT are good places to expand your melon with archery info .
