Sweet, my 3 man team went through R2 Team Rocket and Mahogany Gym without problems.(where I was stuck for over a year)
Fun stuff:
Final Rocket Executive tried to Swagger my Tauros.
I knew that Bitter Berry was useful. Insta-sweeping with Return :V
Pryce's Articuno critical'd my Typhlosion with Bubblebeam. Survived it easily.
I doubt that Clair will be easy, but once I beat the E4, I'm pretty much there since I can restart the Kanto leaders without having to fight the trainers before them.
