Hah! I was just looking through this thread and saw this! SR77 fins sure could take a beating, but about two weeks ago I ate it while I was trying to catch some crappy waves and the edge of a fin clipped the back of my arm. It didn't hurt too much and didn't seem too bad, but the fin box got jammed down into my board and I got a bruise on my arm that was a little smaller than the size of my fist, and it's still showing a little. Had the fin been SR77... well... ouch, that would've hurt!
