I have a Bow Tech Tribute(2006) and absolutely love it !! I actually just got another 2007 Tribute for my brother and i'm in the process of setting it up.(lost a bet and had to buy him 1.. me and my dad split it) But the selling point I don't have a clue... I drew it back also and really didn't see much of a change from mine . And your right.. GMMAT.. I thought the string was tight also. Felt very heavy on the shoulder on pull back for the weight.
I guess it's just another bow to have out there and sell, and make a dollar. ButI only shoot Bow Tech, not saying it's the best but i really like them since it's my thirdone . Hope they sell,butleave theTRIBUTE alone that's all I ask..
My 2 cents
