to answer your question "why is it that 3-cushion billiard players prefer schuler over all other brands?" the answer is this: zero deflection. in my opinion, schuler with it's "super constant" taper/shaft is the only cue where there is ZERO deflection,ZERO, in my opinion every cue has some deflection. predator has around 30% good cues have around 40% average cues have around 50% rotton cues have as much as 90% or more! but the schuler cue with it's super constant shaft has ZERO! now, what does that mean for the billiard player? it means they can shoot with all the english in the world and hard,but aim normally! there is no deflection compensation!!!!!!!! that is why schuler is number one in the world,you never ever have to calculate,or compensate deflection.
This is extremely inaccurate information regarding billiard cues.
Almost all billiard shafts, by virtue of their stiffness and shape (constant/conical), will deflect MORE than pro-tapered pool cues. The harder and heavier woods used to make higher-quality carom cues actually increases the amount of deflection - especially when heavy side spin is involved.
The good news is that while stiff shafts do deflect more, they seem to do so very consistently (less variance from attempt to attempt). Inevitably, the player cannot avoid learning how to adjust for varying amounts of deflection in their game. Any single game of 3 cushion calls for a broad spectrum of strokes. I think that if one wants to do a full study on deflection - 3-cushion might be the ideal subject to observe its various effects; the game requires such a wide continuum of speeds utilizing the entire face of the cue ball.
There is no such thing as a ZERO deflection shaft (at all speeds) so you can stop searching (Sorry, even Schuler doesn't make a magical taper). Therefore, my philosophy is that if you can't get rid of deflection, you probably should make friends with it. Especially if your game involves spinning the cue-ball a lot, it makes much sense to learn how to embrace the natural side effect of it.
I have seen Schuler pool shafts that were "Predatorized". I even experimented with this myself by modifying some billiard shafts (by drilling a hole down the first several inches of the shaft). My "Predatorizing" mod definitely reduced the deflection significantly - although to me, it seemed to produce some erratic spins (ball "flicked" by the more flexible shaft?).
Anyway, I have not met a billiard player that knowingly (or intentionally) uses such a modified shaft. I have spoken about this with both Sayginer and Blomdahl - both are obviously experts at hitting (tiny) targets with a full range of english. The top "ball-spinners" in the world seem to prefer stiffer shafts (over flexible ones) to do their spinning because they can learn to control the deflection.
