one more for speedplays, use them on both my road bikes and track bike. alot of people who tried them and didn't like them didn't ride them for very long. it definitely takes a while to get used to them. the first time i rode them my feet were all over the place and i thought i was going to crash, then i got used to it. the first time out of the saddle climbing, i was sure i was going to crash, then i got used to it. the first time sprinting, i was sure i was going to die, then i got used to it. now i don't even notice.

pedals i've used over the years-
cleats with toeclips and double straps
