Which Clipless pedals?

I would definitely prefer metal cleats or something as close as possible to my SPD-SR which never wear and never disengage accidently. In fact, if you put them up full tension, you don't come out fullstop, even if you crash :O

Try SPD-SL ? You can tension them up nice and high (but obv. not as high as SPD-R), and their pedals and cleats are very durable.
