MVP had a patent pending for their overmold technology for about the first 8-10 years of them being a company. I don't remember the exact timing, but, for the entirety of that time, they outsourced their molds to another company. The molds all said "patent pending" around the sprue on the underside of the disc.
Anyway, when the patent was approved they also happened to move their production in-house, no longer outsourcing. They bought brand new machines for their molds that were incompatible with the old molds used in the machines by the outsourcers. So they "reconditioned" their molds to fit the new machines. Mostly minor changes were made, and the intent was not to change the discs flights in most cases, however there were a few exceptions. According to MVP, several discs had changed from their initial intended flight, and their reconditioning represented them fixing those flights. The Volt was one of these discs, that had, apparently over time, gotten more and more flippy, compared to what they wanted it to be. Anyway, so they make these changes, remove the patent pending and add a patent number to the bottom of the flight plate, and start putting flight numbers on the discs, all in the same go basically.
So, this is where it gets really interesting to me. Previously, MVP only had flight charts, not numbers, but if you asked anyone what a Crave flew like, from the very first Crave produced, to the last patent pending Crave, I think nearly everyone would say like a "worn in Teebird" or something similar. 7/5/0/1.5 maybe if you were to give it numbers. I never once heard anyone say it had flight numbers of 6.5/5/-1/1. But MVP stamped those numbers as the official numbers on the disc when they brought production in-house.
This is where I'm a bit of a conspiracy theorist on this. For 5 years, the Crave was stable and straight, and suddenly we're supposed to believe that its "intended flight" was always -1/1? And this from one of their most popular, if not most popular fairway drivers? I think they messed it up a bit in "reconditioning" but because of the rush to get production ramped up, they stuck to their guns on it and just adjusted the flight numbers. I can't believe that they were that out of touch with how the Crave flew for over 5 years, or that they had let the mold slide by as such a popular disc when it wasn't flying how they wanted it to.
Meanwhile, with the explosion of disc golf due to the pandemic, lots and lots of new players really like the current version of the Crave, because it's less stable, it's easier to throw straight and fits a nice spot in their bag, so if MVP were to fix it now, the plethora of new players probably far outweigh those of us who have been playing from the beginning, so they'd make a whole lot more people unhappy than they already have.
