The free float takes some getting used to, though it's a big help if you have knee issues like I do.

I went from Look (red cleats) to Speedplay Zeros on my road bike and had a bit of a learning curve to keep my feet from waggling back and forth when sprinting. I don't know how they'd feel on my fg.

As for getting out, the action is pretty easy on the Zeros. I have the float adjusted relatively low, so they disengage at about the same point as my Looks did.

The only quasi-PITA is the break in/maintenance thing. The cleats are STIFF for the first few rides. Clicking in is...challenging until they loosen up a bit. Dry lube on the cleats (which are barely walkable - covers are a must) frequently. Every so many months/miles, you're supposed to grease the pedals.

All in all it's really not so bad, but they're definitely more needy than other pedals I've used. And only being able to get out of them to the outside may be a drawback.
