MB to PAP
« on: February 28, 2009, 02:32:21 PM »
What does it determine?  What I've thought is that it tells you the reaction shape.  Longer(4-4.5" or more) = Angular, Shorter(3.5" or less) = Smooth.  Am I close?  If that's the case, what makes it different from pin buffer?  To me that would defeat the purpose of doing, for instance, a 3" MB to PAP and a 1" pin buffer.

Pin buffer distance is, so far as I have seen, only in reference to the pin's position with respect to the VAL. Even in asymmetric balls, the pin's positioning has a greater effect than the MB. The MB's position either by distance or by angle (PAP-pin-MB angle) governs the shape and size of the breakpoint. Beyond a 6" MB distance the breakpoint gets smoother and smaller (angle of entry).

I'm pretty sure pin buffer distance(or angle to the VAL) also determines response to friction.

Besides what you stated about a MB distance of 6" or more, was I correct in my assumption about what distances do what?

I was giving every detail as what a pin's location can affect.

Pin buffer is a way of specifying height of the pin above the midline. Many people believe that that's primary effect is length but it really is what you said: the higher the pin the faster it will go through the skid/hook/roll cycle - snap!

If 2 balls are identical except for the pins closeness to the VAL (shorter pin buffer), the the shorter pin buffer will have a "quicker response to friction", that is, will be snappier at the breakpoint. (for example, both having 4" pin to PAP, but one being 1.5" pin to VAL and one being 3" pin to VAL.)

Both pin posiiton and MB position affect the ball's reaction together. One does not defeat the other. The pin just has a greater effect than the MB. The MB still has an effect, and a significant effect. The stronger the MB rating, the stronger the effect.

If you put the virtual MB of a symmetric cored ball in your track, you will still get a backend. If you put the MB of a very strong Mass Bias ball, like one of the newer MoRich balls (the Nsane LevRg has a MB rating of .035"), in your track, you may get a straight ball or so straight you'll wonder what the driller did.
