I bought a Vendetta Particle Pearl off ebay for a whopping $5.99 knowing full well the pin is almost 8 inches from the cg. I figured it would be an interesting challenge to drill up properly. After diddling around with several different layouts, I thought I would try the pin about 5 inches up from the fingerholes, stacked. I also placed pin 6 1/2 inches from my pap and the cg about 6 inches from pap.

What do you predict this layout will do? Do you have a better suggestion for a layout?

If that puts the pin on the other side of your VAL, you have a ball that will flare backward I think. You might want to think of inverting the ball. Mark an imaginary pin on the opposite side of the ball and use that. That will give you a pin in the 3-4" range. I've done this several times and works great. Those were balls with symmetrical blocks.

Wow. Holy crap. You could also try the Tommy Jones trick layout.

Pin way up and out from the fingers, mass bias next to the thumb, then use a weight hole. This will be a little stronger than the layout you described if I'm not mistaken.

How much TW?

Let me go weigh it. I should probably make sure the cg is properly marked. Does anyone recall a posting on here recently about an easy way to find the cg? I've always started with the mark up and just diddled around with it until I find the cg. I remember seeing something about drawing 4 lines forming a box while shifting the ball on the scale and then the cg is in the middle of the box.

I believe that is the method for finding the cg on a lane 1 ball. You might go th their website and see if you could find that info there.

Since the ball is an 8 inch pin out, and ball circumference is 27 inches, you could draw a line 13 1/2 inches long from the real pin back through the cg and use that as the "virtual" pin position ( inverting the weightblock ), but that would still leave you with the cg 5 1/2 inches from the "virtual" pin position.

Just thought of something else. Depending on the amoung of weight at the cg, and your grip length, you could put the pin 2 inches above your bridge and the cg below and to the strong side of the thumbhole, then drill out the cg back to legal by using a slight variation of the "dual thumb" drilling.

Figuring the pin above at 2 inches, then the total span length of around 5 inches ( from the top of the finger holes to the bottom of the thumb ), and considering that the cg would be swung out to the strong side a bit, you might end up with a pretty decent ball.

with the cg close enough to the thumbhole, the thumbhole would work in conjunction with the added weighthole to help remove the excess weight that might end up in the thumb area with this drilling.

Here is sort of what I am talking about.

I'll go with this...sounds like a pretty good plan. Thanks!

If you go with a high pin layout I'd strongly suggest making sure the pin ends up inside your VAL.

You need to weight it to find the actual CG location. Until you do that, all layout possibilities are irrelevant

I did. CG was only an inch away from the mark...towards the pin so it made it easier to lay out. I went with the pin an inch and a half up from ring, pin to PAP is 4 1/2 and CG to PAP is 3 1/2. CG is located left and down from the thumbhole...ended up drilling the weight hole 3 inches down from PAP on the VAL, went with 23/32 and went three inches deep...almost identical to my thumbhole size. Ended up with .5 oz finger weight, .5 oz left side weight, and .5 oz top weight. Now I just have to decide what the final surface will be...currently at 1000 abralon followed up with Valentino's Resurrection. I think I'll go with Valentino's Snake Oil to finish it up.

lay it out with dual angle method, and drill the thumb to china. weight hole way down your val
