If i do 3 inch on femurs and then 2 inches on tibias, at 5'9", would 6'2 look extremely disproportionate? Also how long would it take to recover from both of these surgeries, lets say if i do both with stryde.
Well not extremely disproportionate but disproportionate. I will use a priori judgement here and even without looking at any of ur pic i can say that could be a blunder. I know someone who did ll from 5'9.5 to 6'3 and did a shortening surgery years later solely because his proportions got him comments and he was in depression for a long time after that.
even if you have a big torso for a 5'9 guy it will look very off on 6'2 body. there r so many other factors that 6'2 would naturally have, head size, waist to shoulder ratio, clavicle lengths and widths, hand size, finger length, arm length, feet size, etc.
maximum you should do if you stil want to keep ur balance and proportions is 6 id say.
