for longer distances, i say definitely Time ATAC or Look Keo (not on list). for the shorter jaunts around the block, definitely Eggbeaters for the minimalist poseur look.

in all seriousness, i use Eggbeater 3Ti's on my MTB and like their ability to engage despite my shoes & pedals being caked in mud. they also engage on all four sides. the regular Eggbeaters are affordable so i went with those on my SS.
