I hate to be a fly inthe ointment, but there's a reason they recommend 27 inches for this length longbow. 58 inches is short for a longbow, particularly one with a long riser like a Lee. A long draw stretches and stresses these limbs to the limit. Will they break? Maybe, maybe not. Given the higher quality glass and adhesives going into bows today, it will probably hold together. One thing you will notice fairly quickly is that the finish will turn chalky on the back side of the limbs where they are flexed the most. There's just not enough elasticity in the finish to handle the severe flexing, so it separates. The acute string angle at a 29-inch draw also won't be terribly pleasant to shoot. I'd recommend you try to trade those limbs for a set that's 62 or 64 inches long. Good luck.
