Well, of the two balls you listed it sounds like a coin flip, I have the Domination, and it's a great length and flip ball, stronger than your Pyro, less than the Passion, but if I may suggest a Shift, it may be a better split of the Passion and Pyro. Little bit of particle in with the pearl, and a nice reaction to the pocket. Don't have an Agent, so can't help you too much there....my suggestion is the Shift, but I don't think you'll be real disappointed with the Domination either.
