I ride XC (Drops and rollers generally no higher than 2-3 feet, lots of climbing, singletrack, etc). I do like to get credit card air on my rides, but everything is well within the "trail riding" realm. Sometimes I throw platforms on for goofing around/urban skills practice, but I just feel a lot more comfortable with clipless. This is partly due to my lack of skills with platforms, but meh. When I pick up a longer travel AM or light freeride rig I'll probably give platforms a fair try.
