Has anybody experienced a different sound (loud clang) on a particular iron in their set of these clubs? The acoustic dampening on the set works really well except for my 7 iron which is very loud. I have narrowed it down to the toe area which sounds significantly louder than the rest of the head. I've 'sound tapped' against other clubs and this is the only one. Is there an easy remedy? Can the sound plate on the back be removed and re-seated? I'm guessing it's an epoxy issue on the plate fitting. Many thanks Jeff
