tech, I appreciate your contribution/posts to the forum, but as any other experienced user of this board would say, the crown is infinanintely easier to conceal, recover from with minoxidil or transplants. I can only tell from experience and from the response from others, but the hairline is the first thing that is noticable from a transplant, concealers, etc. i don't know how you/your doctor came to the conclusion it is not but I've been on this forum a loooong time and that is obvious to me. Thats all i can conclude from. Again, please dont take that as an insult to your intelligence but that is my sincere observation.
