I'd never had a really bad pedal strike, but I hit the left hand pedal so hard on a ride earlier in the year that I actually pulled the threads out the crank. I'd only done four or five rides on it. Gutting. I've got a Deore on it at the moment so I'm still able to get out, but It would be great to get the SLX back on it!
If you've got one with decent spline/threads, let me know.
