STS was cool but as DU approached his look went from cool to... eh what? I hated the DU look when he crossed over to the Blaqk do I liked it again. CL is cool as this look seems to be a more mature Davey.
My favs will always be the variations of the Devil Lock from 94-00. The different dying he did for awhile with it. Red was really cool. The era of devil lock was what I became a fan of so its only natural I like that best.
