I've never played a Craviotto kit before so I do not really have the full perspective there and admittedly I may be all wet behind the ears but what I do have is a beautiful Translation Badge Oyster Pink Pearl snare that I about shart my pants when I got the snare cause when are you going to find another one in that condition let alone the rest of the kit.
Unless the Craviattos have a personal meaning, keep the Luddies.
I'm much more of a Ludwig/working class kind of drum guy... and never really even wanted some kind of fru-fru exotic drum kit. Still, I have to admit that everything being equal (a straight trade and the drums I'd be trading for are in excellent condition), I'd definitely trade for that fancy kit. Even though I maybe never had a jones for one of those kits, knowing that I could own one by trading a cool, but somewhat common kit like the Ludwig would be enough to make me want to do it. Unless I have some real sentimental attachment to something, I'll always trade it for something that's clearly higher end... because, why not?
