Usually that's a no-no, or not recommended at least, can lead to some undesireable reaction.

It considerably weakens overall ball reaction, at least in my experience. I tried it once and that was it. ITZPS has it correct.

I tried it once with a Tomahawk Xplosion, ball was the bomb, but my pap at the time was 3*1.5, so there's that lol.

For me, it tames flying backends. I first tried it on a Rule GP2 and shot well with the ball, so I always plucked that drill on subsequent mass bias balls when I decided to drill more than 1 of the ball.

As others have said, the ball will seem weak on the backends compared to other balls. It is a condition/user specific drill that some will love and most will hate.

Hammer has a MB on track layout in their asymmetrical layout instructions.  They refer to it as a Label Layout "Smooth Arc".

Actually, this probably depends on intermediate diff. If it's low, probably doesn't matter. Now if it's .030, that may be a problem. I actually laid out another ball like this, and the intermediate diff was .008, and it was smooth and a big ball. Perfect first ball on the house shot. Moving in was suspect, but keeping it tight without jumping off the friction was key.

If I remember correctly, that was the recommended drilling for the original No Mercy. I think of it as a label leverage drilling from before the days of mass bias.

The no mercy was a z spin ball I believe.... been so long and so many balls ago.  Putting the mass near the track lengthens the hook zone and tends to make an asym act more like a sym.....smooths out the transition from hook to roll.

It's on some drill sheets. EBI I believe depending on your specs, typically, on average I was told it can smooth out the reaction, midlane and backend.

The MB/PSA position acts like a second pin sort of. Rotating about the pin is the lowest RG and rotating about the MB/PSA is the highest RG.   The MB/PSA distance to the PAP can change the amount of flare and how the ball reacts.  On a symmetrical ball, if you put the pin on the track you will have almost  zero flare.  If you put the MB on the track,  that will also make the core not want to flare and remain stable.  But depending on the Pin to PAP distance, that could make the ball try to flare.  So the two can sometimes fight against each other and give a wonky roll.  More times than not it just reduces the flare and smooths out the reaction because it is going to usually put the pin at 1 to 2" to the PAP creating low flare and the MB/PSA on the track creates low flare as well.

Whaaaa.......^^^^^^this post makes no sense.  PSA in the track does not reduce flare it just takes longer for the core to stabilize.  The PSA migrates until it becomes the axis point.  The only thing that reduces flair is a pin position less than 2.75" in an asym.

MB position has nothing to do with pin position in relation to PAP.  That can be manipulated any way you want.   You can have the MB in the track & a 5" pin if you want.
