Well, I already did switch (I'm just kind of giving a follow up here). Anyway I just was not happy with mostly one thing about them and that was clipping in going up hill. Course back then I was a newbie and had just been on the team for a week but still it was frustrating trying to clip in, uphill, at a busy intersection. But over all the main reason that I switched is because the speedplays are "team standard" since everyone has them parts are abundant etc. Overall I am happy with my speedplay zeros they allow more float, they are lighter but still it's a matter of preference.
