I have an 04 Liberty maxed out at 61lbs shooting a 384gr arrow. I've been shooting it hard since i bought it and haven't had any problems at all. I think many of the stories you hear of limbs cracking are from guys trying to shoot light arrows with heavy poundage or either the bow has been incorrectly pressed. I'm completely satisfied with my Bowtech and would not hesitate to buy another one. Matter of fact i have a Patriot on my wish list as i type!
