I just saw your post in the tickets thread. Unfortunately, I am unable to help you on the trade front, which is what you are looking for.
However, if there is a possibility that you would consider selling your Amsterdam ticket, I would love to take it and go to the show with you. Happy to pay over face, get you a few beers etc!
I won't bore you too much, but I'm a longtime fan and 10c member also. Had Amsterdam as my first choice in the lottery, but no luck on this occasion.
Anyway, hope to hear from you.
