Honestly, I've ridden in jointed irons, and within ten minutes of riding, my ankles were absolutely dying. I have never had joint pain so I know it was the irons.
I think the best stirrups would just be plain old phyllis-maybe the make some sort of comfort stirrup pad. I just think phyllis give the best support for your leg. Keep in mind though that I have never ridden in those particular irons, but my experience with jointed irons in the past has been painful. Maybe you can find someone with those irons and try them out before you buy those.
EDIT: I would also like to add that I think you should check ebay, you may be able to find those exact irons and get them at a bargain price. I always check ebay before I buy things brand new.
