Take a closer look at the Video from Marek. It is easy to see and I can confirm it. But I do not have the feeling that this is already felt when encountered with the ball, but only after.
I use a tight closed bridge and I usually am still down on the shot, with my cue in my bridge, for a couple of seconds after the cue has struck the cue ball. I have never felt "tuning fork-like" vibrations in my shaft during that time. If they occur, it isn't something that I can feel.
However, I have had several wooden shafts that had very distinct and noticeable vibrations when you hit the cue ball off center. The vibrations were so strong that it would have been impossible to not feel them. Some of those vibrations may have been caused by the overall construction of the cue, or the materials, rather than the shaft alone.
Whatever the case, I'm content with the way the Becue plays and feels to ME.
I have other cues, with wooden shafts, that feel "totally different" and "foreign" now, since I've been using the Becue for quite a while. Once you get used to the Becue, you immediately notice the "difference" between the feel of it and a "wooden" cue, even though it "hits" and "feels" like a wooden cue. I can't explain what I'm trying to explain because you have to "feel" it to understand the "feeling". It hits like a wood shaft, but "feels" better...like maybe it was some super duper premium shaft of some sort.
I got mine as a "steal"...an offer that I couldn't refuse, so I don't have a lot of money tried up that I'm trying to get back, should I ever try to sell it, so I have no monetary need to promote it. I could sell it for way, way less than what they go for and still get back more money than I paid for it in the first place.
I'm in no way saying that everyone should run out and buy one. I have nothing to do with them and don't get a nickel for anything I say about them, but I have no problem endorsing something that I think is a good product.
In edit:
I just thought of something that I don't know if I ever mentioned in a Becue thread...the LD properties.
I've never really measured how much it deflects. To me, I shoot with it and it goes pretty much where I think it is going to go. If that isn't scientific enough for you, they try one out and give us some Dr Dave stuff.
Before using the Becue as a player, I was using a 314-2 Predator FAT shaft, which I liked and had gotten used to playing with. The LD properties between it and the regular shaft I'd been playing with before that were a bit noticeable, but the deflection was manageable on my old shaft so it only took a little while to adjust to the Predator.
I don't know if the Becue is a lot different than the Predator LD-wise because I was able to pick it up and start shooting with it on day one without me feeling I was making any adjustments.
One thing that I don't like about the Predator shafts is they have a "buckling" feeling when you hit the cue ball hard, even the FAT shaft has that feeling. I assume that "buckle" is caused by the hollow part of the shaft deflecting away from the cue ball. I use a lot of "power" shots and I feel that "buckle" takes away some of the power that you would get from a shaft that maybe had more deflection, but buckled less.
When you hit the ball with the same speed with the Becue you don't get that feeling. If the shaft "buckles", it isn't a noticeable feeling and it doesn't feel like you are losing any power.
I'll leave that up to the pool scientists to figure out and explain.
