Hey guys !

my name is jay I'm 27 y/o I stand 5'1  I'm worried ! Can you guys help !  140lb with short torso

I have decided that I'm going to do LL ,however, I really don't know what to choose : femur or tibia LL

I wanna do 7-8 cm and I'm just worried about a few things :
1- proration
2- safety/recovery
3- side effects

What do you guys think ?  I wanna do this the right way !

Thanks
