I use Time RXS, same as I use on all my bikes, because I only have one pair if bike shoes and am not about to start changing cleats. I actually ride DF more than recumbent, but find the clipless pedals if anything more important on the recumbent. Maybe it is a matter of experience, but initially I had more trouble with my feet coming off the platform pedals my (used Rotator SWB) recumbent came with than I ever had with a DF, and there is absolutely no way I could reach to tighten the straps on toe clips! As far as the choice of clipless pedals, I don't think the criteria are different for a recumbent, except that you can see the pedals without having to divert your gaze. IMO, the Speedplays require more maintenance and are more sensitive to setup and cleanliness than is worth it unless you are racing and the 2 seconds it takes to be sure your pedals are right side up. In addition, Time (RXS or ICIC) have cleats that can be walked on without ruining them, although they are not in the same league as recessed SPD cleats on mountain shoes.
