I loved my SPD's in rock gardens and moderately steep hills. I hated them on steep climbs...which, of course, contributed to my broken ankle. I'm switching back to plain platforms. They seem to be the best compromise for my capabilities, the technical trail sections that I ride, and my confidence level.
The bottom line is that mtb'ing has the potential for injury regardless of the pedals we're on. I always recommend that people follow their instincts. What works well for one rider may not be best for another. Sure, you could experience an injury from toe clips but you'll never know how many other injuries you avoided by not using clipless on super steep hills, (and few people do hills better than you!).
