I played with the new set of Predator shafts a few days ago. The Vantage was surprisingly neat to use (coming from someone who hates thicker shafts), and the 314-3 was a small notch better than its predecessor, with a 'fresher' hit; certainly enough to drive mad those on the fence about upgrading. The Z3 however, didn't feel particularly special. I often play with a Mezz WX900, and I didn't find myself wanting it, or finding a place for it in my case.
