Loved my 607A so much, I bought another with the main reason being to have one in the wings in case anything ever happened to the first one. But I made [what I now think was] a mistake in asking the driller to make it a smidgen stronger than the first ball.  

It could be "operator error" (i.e. my fault) or different lane conditions, but so far the second ball makes it's move too early. The pin on all my other equipment is over the ring finger, but is to the right of that finger on the second (newer) one.

I don't blame the driller, but is there a way I can have the second ball adjusted to be more like the first without complete redrill?  Would a well placed weight hole be enough to delay the reaction?  I always thought the main purpose of a weight hole was for an earlier roll, but someone recently told me it depends where its put. That it could be used to delay the reaction too.

I am not unhappy with the shape or strength of the reaction. I love the flip this ball makes.  But it's still at OOB surface (i.e. polished) and although i can use it earlier in league (on heavier oil), that wasn't what I was after with this particular purchase.

Thanks for any info suggestions.

Placing a weight hole in it, especially in the lower quadrant will make it be even earlier. This type of weight hole makes the ball read the mids earlier and be less responsive to friction.
Surface is what dictates length....so smooth the cover up. Not ALL balls come from the manufacturer with the same finish. There is the possibility of inconsistency with the surface prep.
I would take it back down to 500, then 1000 and the longer with 2000, then applying factory finish polish. Then see how close it is to the other.

Thank you.

I suppose the surface could be different between the two, but both balls were bought from the same driller and both are OOB, and both APPEAR to be identical----except for the placement of the pin.  

Main thing is it sounds like there are ways to delay/adjust the reaction without complete redrill. If it were a dull-finish ball, I would have tried polish already, but since it's already rather glossy (even though I am aware that underneath the grit can still be different), I was pessimistic that this would make a substantial difference in ball movement.

This driller is very knowledgeable and will probably be aware of the methods mentioned so far, and maybe others.  I just didn't want to approach him and ask for a redrill, and I do want just a MINOR delay in reaction or increase in length.

I don't hate the new ball. But if I was talking to it I would be asking it why ot couldn't "control" itself and delay it's flip more like it's "older brother" does.

And thank you "67tbird".

I haven't had a chance to fully absorb the Morich article, but will ook into that, and didnt see your post till after the one I just sent.

I would try surface changes first. They are the easiest to adjust and don't require any plugging or redrilling.

You can easily go over it with 4000 then some polish to try for more length and the same kind of snap on the backend.

Be good, or be good at it.

NO one has mentioned the possiblity of using a polish like Delayed reaction and I know there is another one but can't remember the name.
