@Jules-the Speedplay X series have a huge amount (it feels "infinite" within the useable range) of float. I have a messed up knee, so they work for me in allowing my foot to fall into a natural (for my body) angle. The minus side of all that float is it feels as though there is nothing holding your foot laterally in place. Someone once aptly desciribed the first attempt at out of the saddle spriting on X Series pedals as "standing on ice cubes." It does truly feel like that the first handful of times, but that sensation very quickly fades as your muscles remember to hold your foot in place. My guess is that there'd be little point in you switching to the X series unless you felt that your foot position/general mechanics could benefit from full free float. (I have an extra set of X-Seres pedals I could loan to you to try, but you'd have to have an X compatible cleat mounted on your shoe.)
