Personally, I did not like the Soma double gate oppy clips (whatever the hell that name means). They rubbed against my 1st metatarsi and cuneiform and irritated the hell out of it. Ended up flipping them on ebay.

I run eggbeaters on one bike and MKS touring with clips on another. Power transfer along the downstroke suffers with the eggbeaters because there is a smaller contact area on the pedal. This is why I'm upgrading to a Look or Dura Ace system soon, for those times when I'm pushing a higher gear. Spinning a lowish gear is OK with the eggbeaters, but I do notice greater power transfer and stability with platform pedals. The only weak point for me with platforms is 1) I have yet to find a stiff soled shoe to use with them and 2) pulling up on the pedal near the upstroke is significantly less powerful than with clipless. I could probably adjust for the latter by tightening the straps every ride, but I like being able to enter and exit easily.

good luck
