I am about 171cm and I have a shorter torso but above average length legs.

Would I be able to squeeze out 7cm on the tibias with external if I decided to go that route?

I know I’ll most likely need an x ray to determine the bone length but just in general with the stats I have??

I don’t know if I can justify forking over almost 50k more just for an extra CM on femurs however I know 1cm is a big difference but still.
