On the issue of "soft tissue" thickness
it seems to me this is always a guarded way of saying fat. I think it should go without saying that if you want a strong jawline, you should attempt to lose as much fat as possible and if you are not willing to do this then mostly any aesthetic surgery you get, be it bony procedure or implants, is going to have poor results. Theres a reason there are no chubby male models, and its got less to do with showing off their abs than it does with their facial features.
Honestly I can't imagine someone who is willing to go through the pain and considerable cost of surgery but isnt willing to diet down to a lean bodyfat level first, but people are indeed strange.
