Question for all drilling gurus
« on: November 06, 2012, 09:16:25 AM »
My friend bought a Karma  blue green. He likes to bowl straight up the 8 to 10 board. He has a ball speed of 15 mph and lower rev rate. He likes equipment that is very predictable and not too jumpy. What drilling do you think he should get to keep the ball long and make the turn on the back end? Thanks in advance for any ideas.
Todd.

I would drill it with a 4 1/2" pin from his PAP.  The ball has a symetrical core so it shouldn't be jumpy.  A 4 1/2" pin will give good length but still finish on the back.  Good Luck!!

Any type of label leverage layout should be fine. It's predictable and not jumpy.

The Blue/Green is the pearl, right?  (The solid is blue/black.)
Be careful as the solid is even for most drillings for most people. The pearl has more length and more backend than the solid, as per usual. While it is not generally a flippy ball, I'd make sure the pin is at least below the level of the bridge, depending on his actual PAP (maybe a slightly larger VAL angle than he normally uses).

Thanks for the replies everyone. After discussing the options with my friend he decided to go with a drilling of pin 4 1/2" from pap and cg 5" from pap.

CG doesn't matter unless you are using it to shift weight to add a weight hole.
