Wow, I really doubt that it won't crack. Deep isn't usually much of an issue, I just plug in a few stages then. But with one that wide, yi, I really don't think it'll hold up, besides being major hell to try and cut it when it sets up. You can try, just don't hold your breath.

HAH! I don't know ANYBODY now!
Being in adult leagues teaches you many things.
1. You're not on top anymore, but there are a lot more people that suck worse than you do now.
2. The myth about the youths having an easier shot is NOT TRUE. I'd have an entire ring collection if it was.
3. Drunk adults are a lot funnier than drunk youths.
