What do you think? Did the pro shop drill all the reaction out of this ball?

The Ebonite website said don't put the mb left of thumb and this is right on the edge of the left side of the thumb hole. The pin is above the bridge, the cg about 3.5 down and slightly to the left and the mb marking you can't see because its must be in the thumb hole. My pap is 4 1/2 and 5/8 up.

What do you think?

Thanks,

Barry,

It depends on your PAP, tilt, rotation and ball speed.

(Assuming you mean over the center of the bridge -)
To be honest, with your ball speed, I think this is pretty weak, even regarding the fact that putting the MB in the thumb hole increases the intermediate differential, the strength of the mass bias.

For me with a 5" over PAP and a slower ball speed (medium) than yours, that is the way I have my Striking Motion drilled, except the MB is just right of the thumb hole, making it slightly weaker in the backend. Plus that is the way I was thinking of drilling a Mission for myself to make it weak enough to use on my patterns (that plus a 4000 grit surface

)

"The proof is in the pudding" though. Try it first. I suspect you''d need a rougher surface than stock, possibly P1000 grit or even P15000 grit. And, no that is not the drilling I''d guess for your use, if you had asked me for such.

Also a P3 or a P4 weight hole can also increase the ball''s strength before needing to redrill. Hopefully the driller was smart enough to allow room for such a hole, if needed.

Regarding Ebonite''s "don''t put the mb left of thumb", that''s just general advice. Too much depends on the PAP, ball speed and tilt and the like. For many people, putting the MB left of the thumb hole is the right thing to do. Not most, but many.

That's a general advice for ANY strong mass bias core. Remember that the MB axis is the final rotational axis towards whcih the ball/core wants to migrate towards.

If you put the MB in the track area or beyond (like a label drilling), it can - esp. for high trackers - easily happen that the ball flares backwards, or other funny things happen which simply mess up the whole ball reaction.
Therefore the safety advice not to place the MB too close (or even beyond) the track - anything on the negative side of the thumb would IMHO be not truly "safe".

May I ask, did you tell the driller what type of reaction you were looking for, or did he ask what type of reaction you wanted???

Looks like you got a drilling to go long and be strong yet smooth on the back end....

And are you using this ball polished or at the OOB finish of a 2000 A pad.

For the record....

I drilled this ball and took all the info that Nicanor supplied me with as to how his other balls reacted and their layouts. I chatted with Dino Castillo and used his reccomendations as well as my own knowledge of the dual angle technique to layout this ball. The MB was not far enough left of his VAL to be a concern to me. I was also told by an Ebonite regional player that Joe Farley(Ebonite Northeast sales rep) recommends not kicking the MB too far right as the Mission has an exceptional midlane read.

So who is correct?
Am I wrong for using the recommendations of a PBA Tour rep and an Ebonite salesman or should I have just used my own knowledge and ideas for this layout??

Fron listening to Barry's concerns... Maybe I shout have...

I agree with Charlest, throw it and see what happens. Who cares what thr layout looks like if it works the way you want it to.
