There are many reasons that I like Speedplay Zero's and weight is not one of them. The weight is similar with other pedals if you include the cleats. I ride them mainly for the float and ease of entry/exit. I also like the fact that I've never accidentally unclipped. Once I find a pedal I like I tend to stick with them. I started on Dura Ace/Look's around 1990 and used them for many years up until I bought a used bike in '05 that had Speedplay's. Once I tried them I haven't changed. I'm sure there are other great pedals out there but as of now I see no reason to change.
