Man sure is alot to digest,but I keep on reading what the group suggest to others! My 03 Bowtech at 60 shooting ICS 400 with 100 grain at 29"s must be good enough! since I can put 3 inside 3/4" @30 yards I'll call that good! This bunch keeps teaching if given enough info.Makes me think about putting the 70 lbs. limbs on the Diamond soon as I get in a groove with it and see how it handles 340's!
