Has anyone else purchased 03 concept irons with problems? I bought a set 4-aw after a fitting on August 31. After finally receiving them metal cylinders came loose in the heads of the 4,5, and 6 iron. They have been sent back and to date I have received no communication about the problem, solution, or options. These clubs are $500 each. So far I am disappointed with defects and even more troubling is the communication from Titlest. Don't quite understand it from the "number one golf company in the world".
