Hey guys, I remember around early 2005 there was a "Re-release" of the entire line of Hammers with a more aggressive reactive veener.  I can get great deals on a bunch of the older hammers(Blades, High Revs, Big Blues, Assymetric Diesels) and I was wondering how can you tell which balls were from the "Strong batch".  Is there a special serial number, different color pin, or pigmentation I am supposed to be looking for?
