They've been found all over now, the "Gran Z". I read they are more like an NXT and a 2 piece ball. They are not new, just new to the US and Canada. Tourspecgolf has had them for a while, like a year or two, for some ridiculous price. Some kid on a another forum paid like $25 a dozen or something, thought he was getting some great deal and bought a bunch, only to be told they were pretty mediocre. He was kicking himself.
