Yes, its a crack alright, and it wasn't there when I bought it new in December 2014. Must have happened some time recently, since I frequently inspect my clubs. The pics I could not upload show it in more detail and its definitely a crack. I can feel it when I run a fingernail across it. As I said, I plan to play it til it breaks or no longer hits a decent shot, my performance withstading. Then was thinking of getting a Wishon driver head, but found the z-18 on ebay with a 3 and 5-wood too. Got those on the way. and will switch heads when the time comes. The 3 and 5 woods are a bonus. Talked with Ricky at DTG and he said he doesn't recall any similar problems with those heads, so the one I got off the bay should be good. Problem solved. Thanks to Typhoon for the ebay heads up.
