Latitude (Trilogy)
I'm gonna give most of the credit for Trilogy to Latitude, who's designer designs all of the discs for the whole umbrella.
The reason I throw Trilogy is the plastic and the molds. I could throw a disc that does the same thing in the air from anyone, but Trilogy tends to make a lot of discs with constant angle rims that I find more comfortable, and I release muuuch better than flanged and beaded rims. Their Frost/Fluid plastic is as durable as Innova champ plastic, and has a great look and the best feel of any translucent plastic in the game (unlike Innova champ, imo.)
Westside stamps are cool as hell. Truth was a game changer for me. I successfully climbed the ladder of Swedish cheater plastic to get to 400'.
Innova
Made the discs that made the sport. Sponsored it. Promoted it. You know that saying, "If you love something, set it free, and it if comes back to you then its truly yours?" (paraphrasing richard bach quote) Well, Innova did that with disc golf, and it did come back to them, and it will always be truly theirs, and I'm really glad they're cool with sharing.
The list of great molds is looong. I love Star plastic, and Color Glow Champ is the fxing bomb. Currently bagging Firebird, Teebird and Destroyer in CGC. Just noticed there's a Colossus. Giggity!
Prodiscus
I will be bagging more of this next year. Ultrium is amazing, and the Jokeri is the best addition to my bag this year. Feels like a flatter Pure, flies like a Rhyno. I could not be happier with my backhand and forehand approach game right now.
These guys just need some stamps and some plastic colors that you're not so likely to find on the ground in nature!
