I'd point you to some of the threads pinned in the tech forum as starters... followed up by Easton's tuning guide found on their site... and if you want to get into some really good stuff, order one of George Ryals's tuning dvd's off of www.grivtech.com
Also type in Larry Wise on the google search engine. I believe there is a decent Tech Manual he had put out. I don't remember what it was called. Go to amazon and type in his name or type in bow tuning. Just a thought.
