Hey Lefty,

The layout is going to smooth out the overall ball motion and get the ball into a roll earlier depending on the players stats. The CG just keeps him from having to put a hole in the ball and can pull the after drill PSA into a stronger position if a hole is needed. Yes you will need a low top weight to avoid a hole or drill the thumb deeper/ double thumb the hole and anyone can use it.

Any weight hole in a symmetrical ball that disturbs the core will move the psa closer to the weight hole. How far depends on how much of the core is taken out.....generally speaking, a double thumb hole would be used to make the ball transition faster down lane. Where as a hole down on the val would be a good idea if you are looking to pull the psa closer to your pap.

+1, Tdub. CG will not matter as far as reaction, only in weight hole and placement. Position of the hole will can affect flare, thus POTENTIALLY changing reaction.

@Lefty

PSA's will normally end up around the thumb because it is the biggest hole with the most weight being taken out and, as Tdub mentioned, it disturbs more of the core. However a Determinator would be required to know exact location. There are a lot of variables that contribute to the PSA position, from size and shape of the core to the size and and depth of the holes, both gripping and weight holes. Generally, a hole 2" down the midline on the VAL will be the safest way to "maximize" the potential of the ball and pull the PSA closer to the PAP, pulling the flare rings further apart, thus creating an earlier transition from skid-hook because more of the ball is in contact with the lane. Meanwhile, the vice-versa will create a later transition from skid-hook and push the flare rings together and creating a POTENTIALLY later reaction.

The smooth reaction is due to the ball cover, manufactures ball intention, and pin placement not the cg. Typically on pin up drillings the psa ends up being the thumb hole. On pin down drillings you can draw a line from the pin through the thumb 6 3/4" to get a very close location of the balls psa within 1/2" either side of the line.

The psa/high rg axis will shift towards holes, the low rg axis shifts away from holes.

Typically when you have the cg down near the thumb or just on the positive side of it, it gives you the option of adding a p3 or p4 x-hole.

 @lefty,

Im assuming you are meaning when I referring to the vice versa. 2" up the mid on the VAL will significantly reduce flare, thus making the transition later. Kid also made great points. If you like the reaction try the layout as in the vid to see if you like it. Then all you would have to do is put your stats on the ball to get the dual angles. Then go from there.

Righty,

Great help!  Thanks for explaining.  I appreciate all the other comments 

Thanks.

Great job Scott, wish we had a determinator around here. It really helps answer questions.
