If the top was reasonably low on the ball,he could have shifted the ball for a lefty too. Then he could have put a weight hole out towards the axis near the CG. Here is my awful attempt at artwork.

Remember CG nomadda when it comes to ball motion on these balls-CG maddas when it comes to getting within USBC specs.

The question is not "can it be done" of course it can. What is preferable is the question. I nor any reasonable person, has a problem with drilling an x-hole in a ball to make it legal. But when the ball has a cg going in the wrong direction over 1/2 ", it makes a real difference in the size hole necessary. Compounding matters is the very thin coverstock shell on today's balls, and the "fluff" surrounding the core has very little weight, causing you to have to drill into the core to get any significant weight out, and the way today's balls flare limits the places you can safely locate that big hole.
I would rather change as little as possible the dynamics of a core that someone much smarter than me designed.
What is necessary is for ball companies to start marking the boxes cg left or cg right if the cg is out of line more than say, 1/2", or for them to get closer to getting them all in line. They already mark the pin placement, but it took them 10 years to start doing that.

quote:


  Time to get a new driller. Any MB/CG position can be drilled very effectively. It's the mass bias you're concerned with and not the CG. The CG is off line. Not the MB. If the cg is off line to left you may need a weight hole to compensate. If it's off to the right it will be in your palm. Whats the problem? If your driller is telling you the MB is off line, fire him and find someone who knows about today's equipment. And the reason the ball doesnt hook is becuae he put the layout on it the Ebo says right in the drill sheet NOT to use. The guy owes you a ball.

Agree... read the drill sheet completely, its noted there.

Here's my layout,  and it is great for me.  I have a little more ball speed than average, so we went with a short pin under the ring finger, 2 1/2 " from CG, and the MB kicked out about 3 or 3 1/2 from thumb.  No balance hole.  It revs up nicely in the mid-lane, then really turns hard off of the dry.  Hopefully my artwork does this justice.
