The Gateway Assassin. I took to this disc like a duck to water. Originally likened it to a Stalker, but it's more like a more controllable Valkyrie. Great D and is quickly gaining as much distance as my Crush, though with very different lines.
Probably the Champ Destroyer. Not sure how, but this disc added 50' to my drives. I've tried all kinds of over and under stable discs, but this one was just right for me I guess. Pro and Star Destroyers will be coming next.
