I have a Traverse with 80lb wake limbs on it. When I first got the bow I set it up and it had a HUGE left tear. So I spent some time today working with the top hats and getting it tuned. After a bullet hole was achieved I measured everything and shot it through the chrono. The bow is drawing 83lb and has the 29.5" draw mod on it, measures just over 29.75". Using a 456 grain arrow it averaged shooting 319 fps!! I was super impressed with the way it performed. If my math is right, that is right at IBO while shooting 103lbs of kinetic energy! Just thought I would share because if anyone is looking for an awesome heavy bow set up, this thing is impressive!!
