I have used the non flat style crank brothers in the past, only complaint is that you have limited tension ability. Still if you need to be in and out for the terrain your in and need to have the grip of a flat pedal at those times then this is a nice option. The spikes are nice, since most others with clipless don't offer that. Funny to read others reviews and complaints about pedals not lasting. If you're hard on gear, thats the way it goes, rocks aren't soft and nothing lasts forever on the trail.
