Steven,
Do I think it would be no value? I wouldn't go that far. But for reasons I've listed earlier, it's hard to compare against a ball that was used 10 years ago because the conditions have changed enough.
I think Brunswick tries to fill a gap in their current, and relatively recent, line-up reaction-wise (as does any other company, hopefully) when designing the next ball.
The other thing is to keep tabs on what's selling in the marketplace and try to have something that may be close to that reaction. For that reason they have released with the Rattler (and especially with upcoming releases) a ball that will be very angular for that customer who desires that type reaction.
One cannot completely ignore what the Cell Pearl, for example, has done (think Mallot) and that has a direct bearing on future sales. There have been years when Brunswick's definition of "angular" and Storm's definition (for example) of angular meant two different things.
The fact remains that for every style of bowler, and regardless of core design, a pearl reactive will go longer and turn sharper (assuming adequate friction) than a solid reactive, which will go longer than a heavy load particle cover, and so on.
If I can see that the ball has a low RG core, I'm thinking it's easy to rev up versus the high RG core. If I combine it with a pearl reactive cover I'm thinking they've got a hit. Why? The average league bowler who plays up 10 board has a great chance to make that one hit.
So, in summary, to PREDICT reaction, one needs to look at only a few things. Bowler style, cover, and core (to a lesser degree).
There aren't any "true oil balls" that provide a skid/snap reaction, and there aren't any pearl reactives that are great in heavy oil. Are there exceptions? Maybe. But for the masses I think most companies do well in designing their ball line-ups. Predicting ball reaction doesn't have to be rocket science, although sometimes we make it seem that way. I hope this helps.
