I’m running Powertap P1 pedals with their key compatible cleats. For reasons I was never able to figure out, I couldn’t rotate my heel enough to unclip reliably with anything other than 0 degree float cleats. The longer the ride, the worse it would get.
In the end I’ve spent a lot of time getting my 0 degree float cleats just right and haven’t had any noticeable problems. Having said that, I ride with SPD cleats for MTB & gravel, and those have loads of float - I wouldn’t say it’s better or worse for me. If/when the P1’s die, hopefully whatever I replace them with will unclip easily with 6 degree float and I can just run with a more default setup.
