Works like a charm. Only put the straps on for sprint events, no need on the endurance stuff.
Simplified version of the answer....
Look Keo (or delta) will do fine
SPD SL will do fine
Speedplay road will do fine (if you have the correct shoes)
Avoid MTB pedals and Time RXS is you can
I run a double strap variation of this on my spdsl
