I think there are a number of bike fit experts who would agree with you, Oak. I did a fair amount of research on float some time ago when my knee was bothering me, and consistently came across those who think it's far better to use a fixed cleat that is set up "just so" than a cleat with float. My knee issue was ultimately related to Q factor so I didn't up changing out my grey Look cleats, but I've also used SPDs without problem--so long as I tweak them a bit to get them just right.
