I own an 18" Vault Crash. I am currently breaking it in, and so far, it sounds good! I am not sure if it will take the place of my 16" Hand Hammered Dark Crash, though (I had a 16" and 18" configuration, but I am currently playing two 18"s - the Vault and an 18" Hand Hammered Dark Crash)!
What part of Duval are you from, DuvalsLilJohnLumpkin?
