During the winter of 1996 I had a shop in Columbus Oh. and the fellow who managed Cornfed Reds at the time, George Fleetwood ( George the Dog) of Detroit, who by the way was a very good player and instructor and who's wife Michell Adams, who was a womans touring Pro at the time, came back from a trip to Detroit with a half a dozen Predator shafts. While in Detroit he ran into the inventor of the Predator shaft, who he had grown up with (Steve Titus). Steve gave George 3 shafts for himself and 3 for his wife to try out. George told me that Steve had told him that they made the Predator out of laminations as a selling point. They didn't think the shaft would sell just on it's low deflection ability alone. They pushed that by having the laminations that the cue would have the same spine no matter how it was oriented in your hand. That was the main selling point at the time.
All shafts deflect the cue-ball somewhat. Some more than others is all. I believe it is one of Newton's laws that causes this reaction and it is this same law that is the basis of Predators lower deflection. Here is a chart showing the amount of deflection that was encountered on a number of different shafts.
