Okay after reading your responses, it sounds like a good strategy is this:
FIRST: Attempt a <=20% femur increase. See how I feel as I go. Stop at 20% if can reach. (I need to measure my femurs, but I think it's safe to assume that 20% increase will put me in at least 6cm ballpark).
6cm would put me at 175CM/5'8.9. 7cm would put me at 176CM/5'9.3. I believe I have very average tibia to femur proportions, so I'm not going to bet on anything above 7cm really.
SECOND: Take a year to recover, see how I feel. My only doubt is there's so much bull on US social media about how if you're under 5'10 you're blah blah blah, so I hope that wouldn't still get to my head (I know they worship 6 foot, but I feel that's next level and I am under no illusion I could safely hit that).
I do have a follow-up question:
If you do femur with (top) Doctor A and then decide to go tibia, would a different (top) Doctor B be willing to operate on you? Or do top doctors usually only accept a second surgery on a patient they did the first surgery on?
Example: Single surgery Femur less complicated, so would be comfortable with "A tier" doctor. And then if I wanted to do second operation on tibia, I'd definitely want to go with "S tier" doctor. So like Femur with Mahboubian then second surgery Tibia with Paley.
