core question
« on: January 29, 2013, 07:44:23 PM »
What is the intermediate differential aka mass biased of an undrilled bowling ball do on the lanes? I've heard it helps the ball pick up on the backend, it helps midlane, etc. What is the strongest drilling on a symmetric and assymmetric ball? Lastly, for all who have seen or thrown, the difference between the sync, nano, defiant, and hellraiser revenge based on transition from midlane to backend. I have already asked this question, but no answer. I don't want just early because the iq is the best at that already. Even with a high rev rate of 500+ approx. I need something for thosentougher patterns where I have full control of the lane. The hy-road, frantic, and tropical storm, and taboo spare should cover all but the long patterns.

I look at it in this regard...  The pin to PAP distance controls the first transition from skid to hook, the MB (or PSA) to PAP distance controls how fast the transition from hook to roll occurs.

But how does this relate to an undrilled ball? Still very useful info though.

In correlation to core design, the higher the int. diff., the more violent the reaction off the spot, to put it into layman's terms. For example, The Storm Sync and VGN are a perfect example of difference in inter diff. The Sync boasts the G2 core with numbers of 2.47 rg, .058 diff, and .028 inter diff. The VGN has the M.A.D. core which has numbers of 2.48 rg, .052 diff, and .020.

Both balls will cover about the same amount of boards in certain areas using the same covers but will yield a different reaction shape. The Sync has the potential to "corner" more violently and recover better from deeper than the VGN. As i have seen and explained, guys who cover more boards will want a higher inter diff because as they migrate inward the ball "corners" better than a lower inter diff ball. Thats the relation to an undrilled ball. But as you drill the ball, these numbers will change in correlation to how strong or weak you drill the ball.

Now, be aware that more plays into this notion, like cover, lane condition, the bowler, etc. Just because a ball yields a high inter diff doesnt mean it'll hook off the lane.

Do you make a habit of throwing undrilled balls?

Once you drill holes in the ball the numbers change. If you add a x-hole, depending on the location, it will increase or decrease the numbers even more.

It is nearly impossible to know what those numbers will be after drilling. The blueprint software does give you a very accurate model of those numbers after drilling. Even symmetric bowling balls after drilling have an int diff. Many have one before drilling, though very slight. After drilling, and with an x-hole many symmetric bowling balls will have as high of an int diff as the top of the line asymmetric bowling balls.

When choosing a bowling ball, especially from several different manufactures it is going to be a guess. Your best bet is to look at the bowling balls desired intention as stated by the manufacture and drill on a layout to match up with that and the conditions you bowl on. The rest will come down to surface adjustment as needed.
…… you can't  add a physics term to a bowling term and expect it to mean something.

" Do you make a habit of throwing undrilled balls?"

No. The reason I asked that question is because of what kidlost said. I already know about how balls change after drilling etc. But I'm assuming the stronger the numbers, the stronger the ball can be. Because whatever I buy in the assym. Will be for heavier/longer patterns.

Righty, thanks so much.

That was what I was looking for. Nothing sucks more than when a strong heavy oiol ball dries up your shot. But not enough to ball down. And then you end up with over and under.
