The HH looks beautiful and it's interesting you asked to have them thin it out, as I did the same, for an 18 AAXplosion crash I bought cheap off Craig's list. They thinned it as much as possible without disturbing the structural integrity and it came back looking new and beautiful, opening up a bit faster than before.
On a side note, I've realized the 18 AAXplosion is a much heavier crash than my 17 AAXplosion. I had assumed the 18 would open up with a light touch as my 17 does, but that 1 inch made the 18 much harder to crash for my styles, so I had it thinned out. Its almost like the 17 is a thin crash and the 18 is a medium thin. I've found this to be the case in every 17 and 18 AAXplosion cymbals I've checked out in stores whenever possible.
