1 extra cm may not seem much but damn are my legs really short, when looking down on my legs and imagining 7cm added to my tibs i think that will look way too long.
But I will wait on the x-rays and let the numbers decide.
I know many people here are at 170 and getting LL, may say to not pay attention to proportions and even go for 7cm but I am happy to wear say a 4cm lift to bring me to 173/5' 8", which is 2cm below the male average, which i'm very happy with.
I know lots of guys 169 that wear a 1cm lift (you get 1cm from any formal wear shoes, and various boots like doc martin etc.), its a very common height, sadly i only know 1 other person my height, it's kind of rare and your always the shortest in the room, with LL i hope to become a more common height, but i realize people come here to go from 'a little short' to the male average which i respect, but to re-iterate im more interested in proportions over height and im only doing 1 LL and i wear shorts all the time when inside.
I guess that means femurs would be best as you wont see the scars easily? but I will need to look into that further, seems tibs is the most common option.
