Not the initial batch. It was adverstised as being a special coverstock in conjunction with BASF. It was 'special' - a great ball. When the initial batch sold so well they capitalized on the name and put out a mish-mash of crapola coverstocks with the Spirit label. That was the mix-n-match that you are refering to. There is nothing special about either the blue or black Spirits that didn't have the swirling in the coverstock. I had a couple of "Good" 16# balls, and they were awesome balls, effective on everything but EXTREME wet or EXTREME dry. I gave them away, and the new owners love them. I have a 15# "Good" Spirit that is a fantastic go-long and come back hard monster. I don't know what the additive was that made it different, but it was different, and effective.
