After fingering through the Bolwers Journal, I came across the spin rates of different bowling balls. The spin rate time is the time it takes for a ball to find/migrate to it's preferred axis.

There seems to be a big discrepency between the different balls out there. Some are under 10 seconds, while there are others take over 50 seconds. Some don't stabalize at all..!! Here you have 1 ball with a spin rate under 10, and another that doesn't stabalize at all. Can both be good..? Can they both work..?

So, what does the spin rates tell us..? Are balls that have shorter spin rates better, or ones with longer spin rates..? Does it depend on the condition and/or which condition favors which..? Is it based on a bowlers style..? Is there a pattern between the spin rates and the overall performance of a ball..? What are your opinions..? =:^D

I'm not to sure on this but It would sound like the
longer it takes to migrate, the larger the flare on the ball would be.
So you would want a ball that takes a while to migrate for an oily lane.

Just an educated guess from what you have given.

Flare is usually determined by the differential. Higher diff's = more flare. Based on that, higher diffs would have higher spin rates. But looking at the times and diff's in the Bowlers Journal, that doesn't hold true for all balls. =:^D

Is that article available online?
I would love to take a look at it.

I can't comment much on this because I hardly know the physics of a bowling ball, but it seems, and according to Track's and Morich's website, a bowling ball with a lower spin rate manages to have more flare potential. I think it also translates into more angular, more aggressive reaction to the dry boards. Take the Phenom and the Onslaught for example, with 6.1 and 6.7 second spin times respectively.

Whether or not it's good or bad is above me at this point.

APK, what's odd about that, is that the Black Cherry Bomb has the highest differential, which means it flares the most. But, this ball will not stabalize. The spin rate is off the chart. This seems to contradict what they Track and Morich are saying, as far as spin rate and differentials go.

Maybe I'm wrong, but to me, a lower spin rate would mean that the ball spends it's energy sooner..? =:^D

T-GOD,

That makes the most sense, I was looking for an easy way to express "how quickly those balls react to dry boards", but my mind went blank. I see what you're saying, so most balls (I'll say most for now) with lower spin rates spend energy faster.

What prevents balls like the Phenom or Onslaught from burning up on the backends though??? Most reviewers state these two maintain energy down the lanes. Unless these balls have an abundance of energy and can change direction the moment of stabilization with little loss???

Then again even though the BCB has a flare potential of 8"+, the strong arc of a reaction could dictate a longer spin time???

Just reaching here......

When Bowlers Journal first began to publish spin rates with their ball reviews (several months ago), they included information about how it translated into different ball reaction potential. I don't remember all of the details. However, I think that it said that balls with quicker spin rates would react more quickly to the transition from wet to dry and result in a more angular hook. On the other end of the scale, balls with slower spin rates would transition more smoothly.

Obviously this is only one factor in the equation and many other things will determine the balls reaction. And I don't know what that says for the Black Cherry. If you go by the spin rate alone, the ball would never change direction. I own a Black Cherry and it definitely does make a move.

I would say longer oil and/or keeping the ball in the oil longer will keep them from burning up. But, the "window of opportunity", for hitting the pocket and/or carrying will be smaller.

Meaning that you have to be more precise, in the trasition from oil to dry, with these balls to get them to work. =:^D

Steve,

about why certain balls don't react early...

I don't think that was the question, but we'll accept your response. =:^D

What Keith posted is what I was assuming, but my question for you Plus40 is you really feel something like the Phenom would play well on the Great Wall of China?

If a ball such as that one gets good length like other reviewers/users indicate, do they truly roll earlier than balls with higher spin times?

Again, take a ball like the Blueberry since that core rolls sooner than the Bomb core, if what I'm feeling here I'd think the spin time for it would be high.

I also can see your point on how that would help on heavier oils, because of how fast the ball can change direction, but the Onslaught's recommended patterns are medium to upper mediums.

This is very interesting to say the least.

A ball with a low spin rate lopes and flips, it doesn't really roll, it goes long, but flips earlier when it hits the dry.

A ball with a low spin rate would help with heavier oil, longer patterns, bowler with high rotation, bowler with poor or inconsistant release, over/under or wet/dry conditions.

I think it works with longer patterns, with drier front's, where you need to stand left and throw right. Because the ball lopes and flips, the ball is really inconsistant and touchy on oil. So, this will not work well on over/under, wet/dry or with inconsistant releases, in my opinion. =:^D

You have brought up a good question. I think you should email Mo and ask him to respond here. I am sure he will when he has the time.
