People want new stuff not old. Last year's oiler probably is still a monster, but say you have $300 to blow on your new high performance ball this season... You going to pick the new $249 ball, or the old $249 ball?
Scenario #2, you have $25k cash to spend on a new F-150. Are you picking the 2018 with zero miles, or the 2017 with zero miles? We have to stop acting like the rules of business don't apply to the bowling industry. When something gets long in the tooth/stale, you have to freshen things up. You can't rest on your laurels because "That's still in production and it hooks plenty".
Motiv did the best job of turning itself from a niche company to a "big brand" better than any other brand in the industry since Storm. If you don't like it, don't buy it. They'll listen to no-sales and adjust the business model accordingly, but about 60-75,000 league bowlers are about to buy new equipment nationwide for the fall season.
Let them.
