I have researched this and came to the conclustion that the problem is more likely than not caused but Bow presses. The right press will not harm the limbs. I spoke one of the biggest Bowtech dealers in Ohio about this and was told they have not had Any problems with limbs on the Bowtechs that they work on. They have a special press for vertical limbs though. He also went on to say that over the years Mathews have showed more limb problems than Bowtech and they are also the biggest Mathews dealer in the state. This was from the head of the archeru dept.
