I went to 7 nose locations and the
 difference between nasal septum + donor ribs vs. nasal septum + ear cartilage was 4:3...

I want to get it done in the first session, but
 there are differing opinions on the choice of nose material. The nasal septum
 
has a chance of causing the tip of the nose to sag later,
 and the donor ribs are the same in terms of absorption.
 I'm also curious about what experts think about nose materials (side effects, etc.)
