Has anyone tried placing the mass bias in ones ball track???
-
Usually that's a no-no, or not recommended at least, can lead to some undesireable reaction.
-
What does it do?

Yes

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".
-
I had an El Nino X-It drilled that way.. One of the best balls I ever owned..
-
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.
-
In the track is ok, just don't make the mistake of going past the track. Then you screw with the flare and it won't hook.

Are you saying that on the lane the PSA migrates and becomes the axis? This never happens on the lane. It can happen with high rpm on a determinator. You can look at the flare rings or look at some blueprint track and axis analysis and see that.
I think you may be correct about about my comment about the MB in the track creating low flare. It is probably more of the short pin to pap creating the low flare. But the position of the MB does influence the amount of flare as well. That is why with asymmetrical balls you can have a 5 or 5.5 inch pin and still get massive amounts of flare when you put the MB in an unstable position, 3 3/8 to 4" from the PAP.
-
Everything influences track flare....pin position, mb, balance hole location, depth of balance hole and depth of gripping holes.......why it's important to have someone that understands that when they drill you an asym. You get large track flare with any drilling with a pin position between 2.75" & 6.75" on an asym.
PSA may not get to the point of becoming the axis before it gets to the pins but that is what it is trying to do. Spin time will never be fast enough for the core to stabilize before it gets there........and if it does you are throwing the wrong piece of equipment.

I think you are incorrect in this.
I had a symmetric ball that always finished by spinning up with the thumbhole on the axis as it entered the pocket. On a symmetric ball, after drilling, the thumbhole becomes the psa most of the time.
If a symmetric ball can manage to find its psa before reaching the pins, I have to figure a ball with an even stronger psa, set closer to the pap to start with, would also find its psa before reaching the pins.
(Oddly enough, I also own a ball with a long pin out distance of 5 1/4 inches, drilled pin way up and label in Palm, that spins up on the finger holes as the psa. Weird, but ball works great, and also spins up before reaching the rack)

You are really talking about the drill angle in the dual angle layout system. This angle (relative to PAP) impacts the length of the ball before hooking:
The Drilling Angle, affects the length of the skid phase of the ball. The higher the drilling angle, the longer the skid phase of the ball. The smaller the drilling angle, the quicker the transition into the hook phase of the ball. The drilling angle limits are 10°-90°
Depending on your PAP location, a MB in your track could exceed the max recommended drill angle (greater than 90 deg). Beyond my knowledge level to answer what happens for drill angles over 90 deg, but assume it makes the ball very condition specific and not roll particularly well for a majority of bowlers.

Syms lose tilt faster than asyms. It is close to but not quite completed stabilizing if it's striking. Ideally you would want the ball to hook out at the exact moment it hits the pins. If it hooks out (stabilizes) before hitting the pins........you are using the wrong piece of equipment.
