Mine is the 2005 ProTec but I would be interested to know which one you think is the best after shooting them all. What are you looking for in a bow, technically speaking? When anyone says to me that I should "buy what feels good to me" I hear them saying "I don't know that much about archery but I did take Psych. 101 in collage". The facts man, just the facts.
This is a great site for the facts. http://www.huntersfriend.com/bowselection.htm
