Nothing wrong with the MKS choices. I've used these on my touring bike for thousands of miles. And these on my commuting bike, also thousands of miles. Both are excellent choices, too, although the first are a bit lighter with a thinner profile (and more $$$). (No connection with AEBike, I just chose that website for links.)

I've never seen "double straps"?? I've also never seen anyone tighten the straps down to the point of immobilizing the shoe (well, at least since the racing days before clipless became in vogue). So I don't see the benefit of double straps.... Just keep 'em loose so you can slip your foot out when necessary, they still keep your feet on the pedals and you can still pull up when you feel like it.
