I'm upgrading my clipless system on my roadie, so I'm thinking about putting my old M520 spd pedals on a fixie. I love clipless on my roadie... but how well does that translate to a fixed gear? My main concern is skidding with them, I love to skid. Will the pulling up on the foot when I skid pop me out of my pedals? (I pull with my front foot when I skid, I don't know if you're supposed to, but w/e...)

Any advice into this?

Thanks
