I can honestly say that I will never use straps and traps again, as long as I live...
I have even rethreaded French pedal threads to Imperial, allowing me to run SPDs on all of my bikes and, yes, I do ride them all. The first candidate for that modification was on my 1973 PX10, when I tapped a set of Stronglight cranks. And for me, altering those cranks was a traumatic experience.
