I think I needed a little clarification on what angle you are trying to spin here. Because here, you are saying that a 5 year old ball out performs the new stuff, and I get the impression that you think that is a bad thing, because the industry isn't being innovative enough:
And why does it sell so well? Because it's a good ball. But it's over 5 years old now, and is still outperforming "new and improved" equipment. I'm surprised more people don't see that. A 5+ year old ball is better than most of what they're releasing now, but they never stop and think about exactly what that means.
But here you are saying that changing things just to change is a bad thing, and a light bulb core is just as good as the "gear core" that Motiv uses, so why change for change sake? I'm surmising that you are saying that it is just a marketing ploy:
Cores matter, I didn't mean to sound like it doesn't matter what size or shape core they put in the ball. I meant that core names and their aesthetics are marketing. Does DV8 really get any performance benefit out of the face on their Nightmare core? No. Marketing. Does this new core have to be shaped exactly like that to get the reaction they're after? No, but it looks cooler. Does a ball smelling like something increase performance? No, but it's cool. Do they really need to keep making wildly different cores? No. The lightbulb core still works just fine. Does making it look like a gear change anything? No.
In other words, they could have gotten exactly the same reaction out of the core with a more boring look or name. But is that interesting? No. Just gets hype about something that doesn't matter that much.
Are you saying that they should be more innovative with their creations so that the consumer feels like they are getting their money's worth (as pertaining to the first post);
or are you saying they should stop making new equipment because they aren't being innovative enough as pertaining to the second post)?
The bottom line is, the industry tries to give the consumer what they ask for. Look at how many threads start on here by people wanting to know what is "next", sometimes only days after a ball has just been released. It is a consumer driven market. The same reason that Storm has now released three different versions of the Natural, and now the Pitch Black, all with variations of urethane covers on them. Industry sees a need for it. Plus, you can't over look ALL the many variables that exist with lane conditions and lane surfaces, and oils.
Just look at cover stocks. You put the R2S pearl on the Victory Road, and it is very popular. As soon as you put the R2X pearl on it (the Fire Road), it doesn't do so well. Same core, different cover. You combine that with the evolution of lane oils (I happen to think that the Fire Road rolls like the Victory Road when used on Ice oil, compared to the Victory Road being used on something less slick like Navigate or Fire). But, throw Fire oil on HPL and watch the Fire Road slow down too early and not corner strong enough, hence a bad ball motion to most.
But to be fair, the R2S Hybrid has done well on almost every ball that it was used on. That cover just is really good for most patterns in the medium range. You put a little surface on it for speed dominate players, and it doesn't slow down too much, and polish it for rev dominate, and it doesn't over squirt. For me personally, I preferred the Crossroad over the Hyroad.
I really think the consumer base, and I don't necessarily mean the majority, I just mean the most
vocal which is who buys the most product, seems to want change, and keep looking for the new cover, or new core that is the next best thing, and that is why so many releases. That is just today's society. Look at cell phones. Is the Galaxy S5 that much better than the S4? The consumer doesn't care, they just want the next thing, so Samsung makes it, and places it in the market.
