This is just my opinion but..
We constantly see question about propotions on this forum, many who are asking, and many who claim it is better to be shorter with good proportions than a little bit taller but with "bad propotions"
The reality is no one actually cares about proportions. No one looks at anyone in that scrutinized way some of ya'all are analyzing. The problem with asking "will my propotions look good" is that the answers are already going to be biased because the people answering KNOWS you have done limb lengthening.
Secondly, there are many tall people with just really long legs. A very good example would be Song Kang. I'm 5'6 and I literally have the same sitting height as my friend who is 6ft(he has long legs).
The only real discussion IMO is how much of your fitness and biomechanics you are willing to sacrifice for extra height. If you ask me? None.
The difference between doing 7-8cm on femur versus 10-11cm is not really noticeable on a day-to-day basis. There is no real difference on a day-to-day basis between 177 or 181. The only difference is that the one who became 181 may become crippled or is unable to even hike after 3 years.
Some of you people treat these magical numbers as some sort of milestones, when in reality it really is negligible. Also, the truth is if you're really tall, or you're really short, no one is going to notice anything. I once wore lifts(3 inches) that made me 5'9 and no one actually said anything(all my friends are 6'1ft+).
Some people also think wearing lifts are cringe. But i hate to break it to you, but many designer shoes already gives you a 2inch boost, and every tall guy is wearing them, so you might as well just do it to feel better!
That being said, I am definitely doing 10cm on femur because my ego can't handle anything else
