Mr. Fritz.........yep that's a splinter. You should have seen my Mathews Ultra Max limbs a few years back.......whoa baby.[:-] Picture the entire backside of one limb and half the other looking like that. But that was my fault and a hot bowcase as an accomplice.
I'm seriously suspecting.........and I know people don't want to hear it.

Unless some bad lot of limbs got out I'm suspecting proper pressing issues.
These bows can be damaged in the limbs AND the riser by improper pressing and stresses.
I simply cannot see design or normal durability as a cause.
For example, take "BowTech Shooter"'s full line of demo bows that he totes around to different shops.....I've been with Pat at a few of these shows and these bows are absolutely ABUSED day in and day out. Far more than what one human being could do to them. They've been dry fired, (probably all of them multiple times), dropped, kicked, left out in all sorts of whacky weather and probably have thousands of shots on each of them easy. They all continue to just keep on shooting.....
All of my personal bows , friends bows etc I haven't come across one limb problem.
The common denominator in my mind is how we press our bows. I know Pat takes great care in pressing, as do I and my friends........I probably just passed about the 1500-2000 shot mark on my Liberty today.
I know it's presumptious but maybe these limbs are being unknowingly stressed during set-up by the shops that sold them? I know each will say "No Way" they're experienced etc etc. and I understand that.........but we're talking about new geometry here.
It seems like the majority of these are on basically brandy new bows, which could point to initial set-up.
You cannot treat these VFT style bows like a regular softer limb angled bow, you just can't and that's a fact.
Maybe a training video or such, or a warning sticker for the limbs with a quick pre-press checklist on it is in order? I know this stuff will be discussed.
I know BowTech will take care of the problem with each and every case.......I'm just wondering if we even need to be seeing the problems that we are.
Remember a bad batch of limb glass can happen to any of a number of manufacturers, so if that's a contributing factor, improper pressing will only magnify or enhance the problem.
Oneida,
With your Mighty Mite, if you have a 6" crack in the limb can you feel anything at full draw, or did you notice an increase in vibration when shot?
