As usual, Predator has the lowest deflection ones. That was true of the wooden ld's as well. So if you care about deflection, Predator is the way to go. Of course, to achieve this, they made the shaft hollow and thin, which means the feel is not as solid as some of the other offerings. I heard Cuetec may lower their prices soon. If true, that is great news, because the shaft they make is allready the best or maybe second best to Mezz, IMO. At a lower price the competition will be blown away. The Mezz is so outrageously priced, I cannot recommend it.
The no-name shafts are not so good. I haven't tried one I like yet, and I doubt I ever will. The surfacing is bad and the feel is inconsistent. Buy a Cuetec, and be done with it.
