I've used the speedplay x-type pedals since they were first introduced many years ago and never had a problem with them. I tried the zero pedals a couple of years ago and couldn't get them to work with my custom made shoes, that work fine with the x-type. I never rode with the zeros because I couldn't get clipped in. I tried loosening the screws and still couldn't get them to work. I sold them on e-bay and went back to my x-type. If the zero cleats are that sensitive to screw tightness, I don't want them.
FWIW, my custom shoes have a flat surface and 4 hole pattern, just for speedplay pedals. No adapter plate needed.
