bmx spikey flats, is what i like but if i was to go back to clips i would go eggbeater's. I used to ride with shimano m somthing or other ( red cage bmx style platform with cleats both sides) but i found they got clogged fast and i spent to much time tring to click in and out, i was constanty cleaning and adjusting, falling over for no reason at all, so i went to the bmx platforms. The eggbeaters are so open mud cant get stuck!
