I've never used the egg beaters, but I switched to Speedplays on my road bike last yr, and i really love them. Very easy to get in and out of, and a slight increase in speed when i switched. I have spd's on my mtb, the kind with clips on one side and reg. pedal on the other. I am new to mtb. and i still need the security of not being clipped in if i have to. I also use the mtb shoes for spin classes. Both my road and mtb shoes are Sidis. I have a bunion on my left foot, so I got the mega size (wide) for my road shoes, in a larger size than usual. This eliminated any issues.
