Oh yeah, Groove is the epitome of this thread for me. I still remember the full page ad in that disc golf magazine that went under. It was going to revolutionize distance for noodle arms. Then it came out and no two were the same and none of them were particularly great.Coming in third place for me would the the MVP Shock. It seems to me like it was quickly overshadowed by the Resistor and later by the Motion, and the re-tweaking of the Volt to make it more stable. It's the only MVP disc I've ever thrown that I cannot see putting back in my bag under any circumstances (although I did trade away my Switch and Servo after buying an Inspire).
This would be number 2 for me. Have they changed the game yet?
Bingo. Not only was the disc not anything close to what was promised, but the owner of the company showed his true colors and alienated a group of customers permanently.
Honest question, was the Groove hyped up? By the time I got back into disc golf the Groove was already a punchline.
