I thought as I was myself paying more and more attention to these elements that it is indeed not the things we see first while they are though very important.
When I saw the profile, I had the same feeling than you had: thos profiles are really pleasant to look at.
Yes, the 5539 is so smooth and seems "delicate" one of my favorite for sure. The thing is that, in the end, there are many profiles I could say such conclusion about :p
Thanks Ed.
