OK, we're about to enter a weird realm where not much makes sense and there's a shroud of mystery and confusion. This is like the Area 51 of disc golf.
As you may know Gateway loves experimenting. They have the most prolific lineup of plastics(sss) and they are not shy about moving stuff out to an unexpecting public. And this disc, the Prototype 93, has to be one of the most interesting experiments they've performed to date.
There are no flight numbers. It's an overmolded disc. It has no name, and they've already said it'll probably not be made again. Rumor has it that it's something like an Innova Roadrunner. A 9-speed disc with plenty of glide and turn.
And now you know everything we know about this disc.
As their name implies Gateway is based in St. Louis and has been active in the disc golf community since 1994. When they're not busy help design disc golf courses (the current count is over 90!) they have created a special line of discs including their popular putter the Wizard.
They were the first to develop wide-winged drivers to battle wicked headwinds and currently have over 32 PDGA-approved models available in three plastic blends: Diamond, Platinum and Sure Grip. They've recently started working with hemp polymers which is sure to attract a, uh... um... new market of players.
