I swap back and forth between switchback and tribute and love them both.I have also called bowtech and they call me right back.One thing about this post is you made me get mine off rack and look.I have 80 lbs limbs and only draw 68lbs what are yours? I am sure they will make it good.One thing I have noticed is my switchback is more accurate at closer ranges an alot easier to draw backbut 40 and farther out tribute kicks butt. It cost me about a grand so I keep telling myself it's gonna get better.Sometime I thinkI should have just stuck with my switchback.
