I went for the best of both worlds with platforms on one side and clipless on the other. I looked at a lot of pedals and decided on the Shimano PD-A530 SPD. They are a great looking pedal, well built. I just got my bike and there is too much salt on the roads right now for me wanting to ride my new bike, but I did use them on the platform side last week for about half a mile. They did fine. I finished dealing wiht all the details tonight on the bike and tried the clipless. I leaned up against the wall and figured out how to clip in.
With these dual pedals, I can jump on the bike and go where ever with whatever shoes I have on. When I go for a longer ride, I can put on the bike shoes.
The only thing you may need to get used to is that if the pedal flips to the side you don't want. It's not a big deal if you're familiar with flipping the pedal with your toe for toe clips.
