Well I mean this was the team I beat Red with in GSC, Kanto is not really half the game, there's not a lot to do tbh. It's more like 65-35, Kanto to Johto ratio.
Well here's some examples of Pokemon I used last few playthroughs, I usually finish Kanto around the low 50s. And if I used a Dragonite it would burly be evolving before Red if I don't grind. Which last time I didn't and I had a Dragonair in the battle vs Red.
