there is NO WAY you were able to beat Red at level 60! I had trouble at 75!! were talking level 85 Pokémon that Red has!!! were you trying to mislead me? *suspicious*
take sabrina with normal moves like Return, and you can wait until you beat Blaine to fight her anyway, since Strength isn't needed until Victory Road. Also, Poliwrath will be a great addition. Machoke is up to you - he's still decent.
