Hi Mixie,

I don't have Speedplay pedals, but I do have some advice that I hope will help. When I went clipless, the guys at my LBS set my bike up on a trainer so in I could practice clipping in and out. They adjusted the tension on my pedals while I was in the shop, making them slightly loose at first so it was pretty easy to unclip. I suggest that you have your local shop do the same for you. You'll get much more confident without the stress of falling in traffic.
