The things I absolutely hated when I rode eggbeaters for a day was 1) the clips were way up by my toes and I couldn't use the pressure from the arch of my foot to control the rear end, 2) my feet would rotate slightly in the mechanisms, which made me feel super unstable, and 3) when I needed to abandon ship at a split-second's notice, I couldn't.
I use BMX flats. Diamondback Bigfoot. Plenty grippy. I'll take an occasional whack on the shins over significantly less control any day of the week.
