RE: do a search
Reading this post I just remembered something that happened a few years ago: I was waiting for a tennis court to free up in my neighborhood, right behind an older gentlemen with a very old old Aluminum racket from the 80's. He was playing a much younger guy with the latest gear, and it was hilarious to see how with his beat up racket he was serisouly kicking the younger guy's a**.
If you're a pro it may matter, but if not, and if "you will not see it with naked eye", then chances are you won't see it when you fly either.
