None of them have adjustable tension (like you'd find on SPDs or Looks) either. This is not a bad thing IMO.
X-series: About ~28 degrees of float before you hit the release point. No adjustments whatsoever. I ride Xs and love them. I've never felt like I was going to pull out, and I kind of like the "ice-skating" sensation.
Zeros: 0-15 degrees of adjustable free float. The cleat itself has little set screws that you adjust to limit the float in each direction (inside towards the bike and outside away from it). I'd probably loosen the screws all the way to get the whole 15 degrees.
Light Actions: ~20 degrees (I think) of "semi-adjustable" free float. You can adjust the point at which your foot stops moving by turning a screw on the cleat, similar to pointing an SPD cleat one direction or the other. Speedplay calls it "heel in" and "heel out" adjustment. I used to work with a guy who rode LAs, and he never complained of pulling out, despite the fact that he's way stronger than I am.
Cleat covers are a great idea! Those cleats ain't cheap, nor are they at all "walking-friendly".
Good luck making your choice! I don't think that you can go wrong with any of the Speedplays.
