Hey, no problem. I usually go for Roost on Dragonite, since it helps alleviate the Stealth Rock damage and the Life Orb damage, but since you have Wish on Vaporeon, it might not be necessary, it's personal preference, really. I'd say, go for Dragon Pulse on Heatran, you still hit the Dragon- types you're aiming for with HP Ice, in addition to Kingdra.
