Tarheal great question! Rob gave some good advice.I have taken up the thought also.PSE has a couple of schools one in Arizona and one somewhere in Indiana I believe.All of what I have learned(wich isn't much<img src=icon_smile_big.gif border=0 align=middle>}came frome reading these forums,and several others through the last couple of years,a few books,videos and asking many questions.The most informative book that I have read is written by Larry Wise titled Tuning And Silencing Your Bow.It is jam packed with great info.Also Apple Archery has a video out that Ralph & Vicki Ciancerillo host that is pretty informative.PSE does too.When you get a bowpress and start doing a bit of tinkering you'll also learn many things.Oh yeah BTW website's such as eastons,Hoyt,BO Jackson,and of course huntingnet have excellent info on tung.Bill D&gt;
