GET the most adaptable, usable system for your needs...Your recovery is going to be long...and probably painful...I for one am truly grateful we could pool resources in a way that YOU can get not only what you want, but what you need...and then some!
One thing you HAVE been silent about tho, is HOW ARE YOU DOING? Good, bad, indifferent? We care, you can tell and we worry and you are obtuse about how you are doing..is it set-backs? just plain PAIN? or new wrinkles? I sure hope you've not fallen and are afraid to tell anyone! Well, you know!
More soft hugs and insulating fuzzies to cushion any 'incidents'...I hope you are well past the 'bedpan' stage! [Went thru that this winter w/my knee-very humbling!]
