Mass Bias
« on: April 14, 2009, 03:57:45 AM »
What ball manufacturer has the MB labeled on the ball?

I know it's not necessary to actually have it labeled but I was just curious.

All manufacturers mark the Mass Bias on balls with asymmetrical cores.

several do.  It isn't about manufacturers, it is about assymetric weightblocks having strong enough mass bias that you need to know where they are to influence ball reaction properly.

Echo the above.  Balls that have a significant mass bias (asymmetric cores) have the mb marked.  Those that do not have a significant mass bias (symmetric cores) do not.  To find the theoretical mass bias on a ball with a symmetrical core, measure 6 3/4" on a line from the pin through the center of gravity.  But it will be so small that it won't affect ball reaction, so you might as well just use the cg.  --  JohnP

don't let the mass bias or it's indicator overwhelm you.......a mass bias simply means one side of the ball is heavier than another. this has been going on since balls were made of wood.

I think it is necessary to label it.

Many times we have to special order a ball with a specific MB location.

In fact I wish the ball companies would post the MB location on the box, along with the pin, the gross weight, the top weight.

Most of the time, the top weight is not a big deal,  but the MB location is extremely important to know.  

Having it posted on the box would certainly help when you are looking for a specific MB for a lefty!!!  Or for a righty who does not want a balance hole.
