It is just hard from a Pro Shop to stock the "newest" release when the month it comes out, the next newest piece is on the net. At least when companies release 2-3 every 4 months, the consumer feels their ball will not be replaced in 45 days. Like it or lump it, these practices have hurt Motiv sales in my shop. I now have a Tribal Fire on my wall that is now FOUR releases ago, and is 3 months old.
But look at their most recent releases. They are all different.
Tribal Fire - high rg, med diff, polished hybrid
Jackal - low rg, high diff, asymm, strong sanded pearl
Forza - med rg and diff, early sanded solid
Revenge - low rg high diff, strong polished hybrid
All 4 of those balls can offer completely different motions. Motiv is not a company that caters to people who believe in the newest thing being the best, they release balls to complete a lineup. They seem to be more of a company geared towards bowlers and not just consumers
