The information I've read from other posts has been somewhat helpful on this topic but I was wondering if anyone could provide more feedback on the subject.

The only pedals I've ever had are look keo classics (which I've had now for over 2 years). It is time for new pedals and I've had several people recommend speedplays. I'm a little hesitant because the keos have worked for me this long and despite some minor complaints (trouble clipping in quickly at times), overall I have been happy with them. I'm not sure if I want to spend the money on something I've never tried (although it could be better) and then end up hating them.

For people that have tried both, can you see advantages/disadvantages over one or the other?

Also, do you think the keo sprints are much different than the keo classics?

Thanks.
