It also sounds to me like there might be a deeper issue here. I will be the first to tell you I'm absolutely not a fan of mathews or their bows. However, they seldom have limb problems, even with their super agressive preloaded limbs like on the Reezen. Tell us more about your setup, someone here might be able to help.
Im shooting 67 lb draw with 70 lb limbs so I don't think that would be the problem, also my arrows are 412 grain carbon injexions. absolutely no dry fry or anything like that. nobody has shot my bow other then me. this has me confused because like you guys said you dont hear of mathews with alot of limb issues but they dont ask any questions when replacing them... the 1st set of limbs it was cracked like on the corner and peeled up the side of the limb. this time its cracked by the limb bolt.
Yeah its definitely not you or your setup. I mean I've seen a few sets of delaminated reezen limbs in my day, and a few that cracked, but it was pretty rare. You should be on the horn with Mathews requesting to send the entire bow back and have them send you a new one.
