Pro Billiard Series - Las Vegas Men's Open 10ball live now

J
Just checking the full Predator events in Vegas. The Teams tourney has a $120,000 prize for the winners. Each team does have from three to five players, but a nice payout if you are a three or four-person team if you win it all.

Some of the PLP players will also turn up for the event. Starts two days after the PLP ends.

Neuhausen, Duong, Yapp, FSR, Souto, Capito and Januarta will trek to Vegas from Miami after the PLP is over.

Jump Cues

Basically, I only compete in one pocket. I am considering the prospect of dusting off my 9-ball game. These days, I think rotation players have to be proficient with a jump cue. Accordingly, I am considering an investment in a decent jump cue. I am interested in your recommendations on jump cues if you have them.

I am particularly interested in any insight on a comparison between the JFlowers JMPR and the CueTec Propel. Most things I have found so far, suggest the cues are comparable, but the Flowers cue is a bit cheaper.

Thank you in advance.

Oh man! Once I started breaking out the jump cue in one pocket, my shot options nearly doubled! Good thinking.... :]

Diamond table domination

Unlike Predator and Rassoon, I think Brunswick has a shot at biting into Diamond's marketshare. (ironic!).

About every week on FB I see another room that has just bought 10 or so new GC7's. I just saw one 5 min ago and that's what brought me back to this thread. I never saw any of that with the other two brands.

For so many room owners to buy the new GC7, that means pricing in bulk is much better than individual retail, and it means those room owners WANT something other than Diamond.

Also, unless Diamond has changed in recent years, their price for buying 1 table is the same as 30 tables.

New GC 7 is available at 4 1/4 4 1/2 and 5 inch corners - no 4 3/4 - personally think that they should have gone with the 4 3/4 instead of a full 5 inch corner - I think , for a room , the 4 3/4 is a perfect compromise for the majority of tables in a room-

Spin-to-Speed or Revolutions-per-Foot?

See my non-math-physics posts above with the links. This physics-based stuff is incredibly useful in real-world situations.

To make it easy, here are some of the examples listed above:
90 degree rule tangent line
30 degree rule natural angle
3-times-the-angle system for good action draw
40% Rule for judging gearing outside spin
ideal tip contact point to get maximum sidespin reaction with a drag shot
ideal tip offset to get maximum SIT
ball gap size where cut and throw cancel over a wide range of angles
optimal tip height on a lag shot
Coriolis System for aiming swerve and massé shots

P.S. - Thank you for all your contributions to the game, it's great that someone works hard to inform everyone of all these nuances. Your 8b and 9b breaking videos from a few years back had excellent information.

You're welcome. I aim to swerve. 🤓

Spin-to-Speed or Revolutions-per-Foot?

RPF definitely increases linearly with tip offset. The math and physics is here:


where SRF is the spin-rate factor (spin-to-speed ratio), omega is the angular speed in radians/sec, v is the ball speed, R is the ball radius, and b is the tip offset from center.

Speed is related to distance (d) and time (t):
v = d / t​
So:
SRF = (omega * t) * R / d​
The first term is related to revolutions (rev) according to:

(omega * t) = rev * (2 * pi) [there are 2*pi radians per revolution]​
So:
SRF = (2 * pi * rev) * R / d​
So revolutions per foot (RPF) is:
RPF = rev / d = SRF / (2 * pi * R)​
with d and R measured in feet.

The ball radius (in feet) is:
R = (2.25" / 2) * (1ft / 12") = 1.125/12 feet​

For an assumed maximum spin at the standard miscue limit of 0.5*R,

SPF = (5/2) * (b/R) = (2.5) * (0.5) = 1.25​
which gives:
RPF = 1.25 / (2 * pi * 1.125/12) = 2.1 rev/ft
​
If you roll a ball (SRF = 1) and see how many revolutions it makes in one foot, you would observe:

RPF = 1 / (2 * pi * R) = 1.7 rev/ft​

Of course the math and physics can be applied, but how useful is this in a real world situation? Simply, it's not. Between the acceleration of your arm, tip offset variances, tip/chalk friction coefficient, and all the human error, you can only approximate but never accurately define these conditions.

Then you add in stress to a given situation and any reasonable consistency goes out the window for your average player.

P.S. - Thank you for all your contributions to the game, it's great that someone works hard to inform everyone of all these nuances. Your 8b and 9b breaking videos from a few years back had excellent information.
