I had MKS EZY's on my Swift till this week.
They worked great for me w/my Mu, but when I changed'm over to the Swift, I had 2~3 sudden 'pop-offs' a week...
(NOT good seeing a pedal go flying off into a busy road, or mashing down at a start, and having the seat catch you at the groin... )

I figured out why I was gett'n sudden pop-offs; it was caused by me wiggling my feet more to get a snug fit into my PowerStraps, in combo w/harder pedaling.
With my Mu I didn't pedal as hard (more upright), nor wiggle me feets to get a snug fit as much as w/the Swift.

I've up't to Eggbeater's & after a couple days, I'm impressed.
~ They're not detachable, so I'll leave it at that.
