BKloss....you need a longer pin to get the CG down towards the thumb more and avoid excvessive fingerweight when the weighthole is added.

My uprising has a dt drilling. It makes the ball extremely strong by raising the diff. The reaction depends on the ball. For example, it will be the balls natural reaction but about 5 ft earlier and 5-7 boards more.

I had the pleasure of watching Mo layout that drilling on my pro shop guys kinetic energy. Mo is a genius!

With this drilling is there any modifications needed for someone who is a high tracker?

High tracker is affected more by the pin position....not this weighthole as the primary factor.

One should go to the Mo site and get the two concepts.

They are fantastic.

1. Dual Angle Seminar

2. "" class="bbc_link" target="_blank" rel="noopener noreferrer"> Gradient Line Balance Hole

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,

A quick question to all...

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!

Pitching the weighthole will help remove a marginal amount of weight from a different part of the ball which will help alter the rotational dynamics of the core.

The direction of pitch can help alter the ball reaction...rev earlier, rev later, more backend, more roll.

Greetings!

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
