Stirrup suggestions for bad ankles and knees

Hi!  I'm a longtime Ridecamp lurker, this is my first post.  I think I (finally) found a saddle to fit my Arab (Ansur Safari--
I'll let you know how it works out once I've had it a while), but now I need some new stirrups for me.  After riding in
regular English stirrup irons, my ankle hurts.  I also have bad knees, and while this hasn't been a problem for my riding
thus far, I'm sure as the distances get longer it'll become a problem (it's slowly making its way up my legs).  So I've been 
looking at the Trail Tech, Cloud, and E-Z ride stirrups, also the Herm Sprenger jointed irons ($$$!).  I'm tired of buying
things and sending them back (I did it with about 10 saddles), so any comments would be helpful!

Thanks,
Abby (ouch!)
