Even when it's Latios vs. Latios, going toe to toe in a Speed tie is never fun, especially in doubles. That's why if people use something like Hydra, Mence, Chomp, or Latios, there's normally a TWaver or a mon with Icy Wind. Since you run TR, those options might not be the best. At the same time, using TR so Hydra outspeeds those mons is a futile attempt, as the original point of Hydra was to have something fast without TR.
