Walking noob here, so take this with a grain of salt, but -

Short answer: you should be fine with either Flaming Rock or Volcano.

Long answer (that's possibly bad advice): While category alone has no bearing on what you'll get, categories DO still matter, a teensy bit. This is why I shoot for breeding pairs with a common element like Terra or Flame instead of using double opposites - the probabilities are better, and if you don't get the dragon you want, what you do get is more likely to hatch quickly. For example, if we want Armadillo:

Flaming Rock OR Volcano + Medieval = Flaming Rock OR Volcano OR Medieval OR Armadillo = 25% chance at each. Flaming Rock and Volcano hatch in an hour or less, IIRC. You might get Medieval, but eh, can't win 'em all.

It gets hairier when shooting for Soccer/Cool Fire; you have a chance at Alpine Dragon with a 16h breed/hatch, which sucks if you're unlucky. Buuut, you might get it with Volcano/Platinum anyway, so there's that. As they say, pick your poison :P

In any case, good luck, and happy breeding!
