I know that limb issues are kind of

, but I can't help but vent my frustration here. Several months ago my Micro 335 developed a crack in one of the limbs. Excal, of course, did the right thing immediately — customer service is amazing, and they have always done right by me. Those limbs had seen moderate use for 2 years. Yesterday I cocked the bow and once again heard that tell-tale cracking sound. The right limb not only cracked, but was beginning to fold over. These limbs have had MAYBE 50 shots total, no trauma or abuse. I'm sure Excal will once again step up, but this kind of shakes my confidence in the brand, especially in the face of the Destruction Challenge marketing — you mean I can run my bow through a swather after shooting it out of a 17th century cannon at a brick wall and keep hunting, but woe be to me if I just try to cock the thing?
For stats, I shoot arrows with a total grain weight of 385. I keep my string 1/4" off the riser. These particular limbs have only seen a factory endless loop string. I never leave the bow cocked for more than the 1 or 2 hours I sit in the stand. The bow is stored in a well ventilated room and never gets hot. I've been shooting crossbows for over five years now, and I'm certain I'm not inflicting newbie abuse on the bow.
I have wondered if the decocking process isn't as good on the limbs as it is supposed to be. I follow the right procedure, loading the string with my arm before letting the power out of the limbs gently, etc, but... I guess I'm grasping at straws. I wouldn't say I'm a rabid decocker, just after unsuccessful hunts and when I change/adjust the string. Once or twice a month?
