Is this good?
Would you use this?
For how long will this work?
When you use this you will not need any triangle rack after, but is this good?
Mr.RS4:
Not a fan of it, sorry. Reasons:
1. With that device, you are DIVOTING the cloth. You are, in essence, injuring the cloth -- the same way that jump and masse shots do (except that you're doing the jump-/masse-shots in the same place on the table every time -- the rack area).
2. Those divots won't stay in their precise places for long. Unless the table is kept in a room with meticulously-controlled temperature and humidity, that cloth is going to shrink and stretch. Where at one time the divots were in the perfect spots to have all the balls lean up against each other, after a period of time, the divots won't line up any more, and the table will have to be "re-tapped" -- putting more divots into the cloth that are in close proximity to the previously-pounded divots, compounding the problem. In a tournament setting, this isn't a problem, because the cloth gets changed at regular intervals
anyway -- probably before each tournament, in fact. But the poor home and room owners are going to curse this device for moon-cratering the racking area of their table's cloth over time.
3. For gentle break games like 14.1 or one pocket, those divots may cause problems in slightly redirecting the natural path of gently-hit balls through the rack area, especially after the balls have already been slightly broken up, and the player is trying to play a safety in the rack area. (Obviously, for power-break games like 8-ball and short-rack rotation [e.g. 9- and 10-ball], this point is moot.)
4. That's also why you'll never see tapping used in snooker -- they *always* use a triangle to rack the balls, because of the prominence of gently-hit safeties used in that cue sport. In fact, when the referee is replacing a pocketed color ball (i.e. because there's still some reds on the table), the referee *never* places the color ball directly onto its spot -- instead, he/she gently places the color ball on the cloth a slight distance away from its spot, and gently rolls/rocks the ball
onto its spot. Tapping would injur the nap cloth used in snooker.
I'd say get a good quality rack (e.g. Delta-13 with the leather noise cancelers, the
True-Rack, or the Diamond rack) and LEARN HOW TO USE IT CORRECTLY.
