I just built a bike and considered clipless pedals for it. I've always hated toe clips, so I definitely wasn't getting those. Then I heard about the clipless/flat combo, but I heard that as a clipless pedal, theyre not the best...and as a flat pedal they werent the best either. You're paying for flexibility, but mediocre versions of each pedal @ best.

They probably look tacky to some people but I ended up getting these...you have to twist your foot in to 'engage' the strap kinda like a clipless. They work pretty good actually.
