Putting the x-hole in that location will dramatically increase the flare potential and MB, if my information is correct. I'm not 100% sure, but what I can tell you for certain is this:
1) The drilling sets up a more dynamic ball reaction (FYI, that doesn't mean go long and turn left)
2) The balls I have seen drilled this way hook...ALOT. They don't roll right away, but they quickly pick up and are very continuous throughout the entire lane.

can this be done on ANY ball?
(Ex: Kinetic = Skid/Snap so which this drilling it would be stronger and more constant?)

--------------------
It can be done on any ball. That being said, I think you should look for some pre-drilling specs. A longer pin is typically required.

Reason is because I just bought an NSane Levrg, sitting on the wall waiting for me...its in the range of 3" top is 3oz

By drilling the "second thumb"/x-hole, you end up taking a lot of weight out near the thumb. In order to keep everything legal, and keep the x-hole location you want, you need to start with more weight near the thumb...i.e., the CG closer to the palm/thumb area...if that makes any sense. That was the explanation provided to me by a driller who has done several of these on customers' balls.

You do not need a longer pin but if shorter pin it will be pin under ring or bridge, it will increase the midlane reaction and backend. The cg will land right above the thumb hole and yes legal statics can be an issue with the wrong weighted ball.
We used this on a Pantera, Tiger, 3D violet all made me look like my rev rate went up 50-60 rpm's, at the time i was lucky to be 230-250 rpm area. I went from not being able too hardly wrinkle a ball to a decent amount of hook set reaction.
The one thing that you have to watch out for is the ball will just poop out with no oil, roll out becomes an issue because the core has used almost all energy early getting the ball to kick in.
generally games 1 and 2 were safe and game 3 was a ball change to something drilled pin high.

what would i be looking at and where would the pin and everything have to fall to do this drilling

One should go to the Mo site and get the two concepts.
They are fantastic.
1. Dual Angle Seminar (http://"http://www.morichbowling.com/MosCorner/DualAngleSeminar/DualAngleSeminar.htm")
2. Gradient Line Balance Hole (http://"http://www.morichbowling.com/MosCorner/GradientLineBalanceHole/GradientLineBalanceHole.htm
")
Both of these ideas can be found at the www.morichbowling.com website under the Mo's Corner. The dual angle technique is July 2007(high tracking discussed THERE). The gradient line is the April 2008 seminar.

PS then following on to the videos above of Fred Carroll with the different drillings. Title is Ntense LevRg,

I've been seeing a couple of videos in YouTube (Mo Rich balls) where this drilling technique is used.
I've read the Mo Rich document (Gradient Line Balance Hole)... and I have a question...
Do you call "two thumb" drilling to "any" balance hole made in the gradient line or specifically the one you drill in the "P3" spot?
Or this technique is some variation of the "Gradient Line Balance Hole" depicted by Mo?
Thanks!
Post by: chun914 on October 02, 2008, 10:26:36 PM
And are the any recommended size of the balance hole ?
Post by: Doug Sterner on October 04, 2008, 01:13:33 PM
The direction of pitch can help alter the ball reaction...rev earlier, rev later, more backend, more roll.

Lane 1 Buzzsaw...The Official Power Tool Of Bowling
Post by: srlunatic on October 04, 2008, 01:23:13 PM
I have just drilled my Cell with a "Double Thumb" drilling....or more precisely added a Weight Hole in the P4 position which is on the MB. I believe this is the location for the Double Thumb drill. Originally I had the ball just drilled 5 X 3 and had pretty much 0/0 in static weights. Loved the roll on it but couldn't use it on anything other than a serious flood so decided to punch a WH at P4 (MB)...I used a 29/32 and drilled a bit short of 2 inches. This ended up with about 6/8 finger and 5/8 side. Took it out to the lanes and gave it a shot...The ball cleared the heads instead of seeing PAP migration at about 8 feet...and when it hit the break point it was a much more pronounced move. By drilling at P4 (MB) you are increasing the differential so you should see more length and a more aggressive move off the breakpoint. This is certainly what happened with me and my Cell. Still too strong for more than a game on a house shot but does give me a lot more length and stronger turn with the weight hole.
Hope this helps!
Mike
