Thought I'd start a new thread about this and add some pictures.  Take a look at these two layouts and see if I am understanding the angle of the MB correctly.

The MB is in the same location on both layouts but the pin has been raised on one of them obviously changing the length of the pin from the PAP, but also changing the angle to the MB.  On the pin down layout the angle is approximately 75 degrees and the pin up layout is close to 45 degrees.  If I am understanding this correctly, if I wanted to get a 75 degree angle in a pin up ball, I would need to move the MB to the negative quadrant of the thumb.  That would result in a week layout wouldn't it?  I still think I am not understanding how this angle is measured as it doesn't seem possible to layout a pin up ball with a strong MB according to my reasoning and I know people talk about doing that.

CG nomattaaaa!

The mb is not like the cg, it is a set distance from the pin (1/4 the circumference of a ball.  CG's can vary from less than 1" away from the pin to more than 5" from the pin.  As to your other post, pin distances really don't have much of an effect on ball reaction, other than the face that different pin distances open up different possibilities for weight holes.  In certain instances combinations of top weight and pin distances make certain layouts undrillable.

PAP ---> PIN

AND

PAP ---> MB

yes, overall reaction comes from a combination of the 2 distances

the PIN ---> PAP being the primary effect (flare & length)

the MB ---> PAP being the secondary effect (breakpoint shape)
