What is the best use for a 1:30 Label leverage drilling for a righty? Meaning PIN beside ring finger, CG near/at grip center, and MASS BIAS (if there is one) either under the thumb or to the left of the thumb.

As in - who best benifits from this drilling (either, players with strong side rotation or up-the-backers with minimal side rotation)? Is this drilling basically a "down and in" type drilling or a "swing the boards" type drilling?

Also, what lane conition is this drilling best suited for... Heavier Oil, Medium Oil with Strong Backends, etc...

Thanks!

That drilling is made to have good length with a strong backend(depending on the ball and PAP)

Mainly better for tweeners or crankers, and depending on the ball it could be used for heavy oil or light oil)

Ric,

You are making an unwarranted assupmtion that the pin next to the ring finger is leverage. It is not is MOST cases. It matters less how heavy the oil is inside; it matters how much dry or how clean and how long the backend dry area is and if it needs to be controlled.

In general a 1:30 or more correctly, a 105 degree drilling is effective when the backends are screaming (hooking a lot) or when a bowler's rev rate is much higher than his/her ball speed rate.

Well, here's my reason for asking this question:

Important Information below:

-------------
I have slightly (not much more, just slightly) above average speed which is measured on the monitor near the 42ft mark at about 15.3-15.6 mph. I have slightly lower revs with about 40-45 degrees of Axis Rotation.

My friend has medium speed of about 14.8-15.2 mph. He has above average revs and a strong side release of about 60-65 degrees of Axis Rotation.

We have similar PAP's.
-------------

2 months ago I took a brand new to my ball driller (he drill's for some pro's and some regional's) and told hime that I wanted the ball to get plenty of length and have as much backend as he could give me, basically "long and strong"!

Well, he put's the PIN beside, and half way into, my ring finger and put's the CG 1/4" right of grip center and no weight hole. Basically a 4 1/2" x 5 1/4" layout... (sort of like a 1:00-1:30 layout).

Just about 2 wekks ago, my friend takes the same driller a brand new ball and tells hime the EXACT same thing as I did, "long and strong" with the most backend possible!

When he get's the ball back, I expect it to be drilled similar to mine... BUT... his ball has the PIN above and slightly left of the ring finger and the CG about 1" right of grip center with no weight hole. Basically a 5 1/4" x 4" layout... (sort of like a 10:30-11:00 layout).

Just wondering why we got 2 different drilling's when we asked for the same EXACT ball reaction??? The driller has watched both of us bowl so is it maybe that our styles "called" for the driller to give us different drilling's?

Just trying to figure out which drilling's will give me the most backend reaction possible for my speed, revs, and axis rotation. I think that I was once told that my release, "says" early roll with an arcing backend reaction... so on Medium Oil or Drier Oil, I'm always looking for balls that give me alot of length with the most backend reaction possible.

Charlest said the following:

quote:
In general a 1:30 or more correctly, a 105 degree drilling is effective when the backends are screaming (hooking a lot) or when a bowler's rev rate is much higher than his/her ball speed rate.

So if that's the case, then it looks like the driller should have given me the drilling that he gave my friend and he should have given my friend the drilling that he gave me... correct???

I trust my driller... but I'm just wondering about some things.

Thanks!

If you guys want to learn more about drilling , pin position, layouts, etc... Go to these two sites and read up a little more on what influences the balls reaction and that will help with the communication with your pro shop guy. http://www.bowlingfans.com/jeff/ballreactionbasics.html and http://www.rollrite.co.uk/secrets.php .hope this helps a little.

Rick,

I've written quite a bit in the attached thread about axis rotation and drillings.

Also messaged you privately on this.
