I've used Speedplay X/2's for years and highly recommend them. Two years ago I decided to try Zeros and the limited float aggravated some fitting issues I had. I then got properly fitted and went back to X/2's and haven't looked back. What is the reason to limit float anyways? X/2's are just fine IMO. Another tip, instead of plastic covers to protect your cleats, you can apply some shoegoo to the contact surfaces and that will extend the life of your cleats a bit. Once it wears off, just apply more.
