MB for dummies
« on: November 14, 2017, 02:32:58 PM »
Does anyone have a good explanation of how and why an asymmetric core changes the ball motion and reaction compared to a symmetrical core?  And yes, I know all drilled balls are asymmetric.  I've read all of the generic placement information.   I'm looking for a more detailed explanation.  Are asymmetric cores better for some releases, speeds, and revs than others?  Is the reaction different for a strong released high rev player versus a lower rev player?

Excellent technical article showing exactly that on Storm's website under the news section. There's some really good stuff there.

There are others that will give a lot more technical data but my 2 cents as a low rev speed dominant bowler is 65x4"x30 with a double thumb hole on a mass bias ball is just the ticket for decent to heavy oil volume.  Only attempt if strongly speed dominant.

I have used that drilling before . I found that the ball would react too quickly and roll forward if I didn't really get around it.

Yeah that is the drilling to use if bowling balls never seem to react too quickly for your style and polish is not your friend.
