I was okay with platforms. I tried toe clips and they chaffed my toes without mercy, so tried Power Grips. They're good. They did make an impression on the instep, so I went to a Shimano clipless on one side and platforms on the other. I now wish I had gotten a similar pedal with clips on both sides, but it's not enough of an issue to scrap a good pair of pedals. I'm using the Answer bmx shoe on a Giant Cypress, by the way.

Well, I fell twice in the first two days, so it seems to be a very short learning curve. I would suggest you get a feel for them before playing in traffic.
