I think you need something weaker than those balls. The Bronze Centaur is not exactly a weak ball and if that's the weakest ball you have, then there's plenty of room underneath it. That your Pyro is 4000-grit plus polish (what polish?) and you're all the way left only makes me think that's even more true.
A weaker ball will probably go a long way to conserving energy, get you standing back on your lane and not the next one over, and not rolling out so readily. A Hornet, Neptune, or Venus would fit under the Bronze Centaur and the Pyro. If you're a Storm and Visionary guy, the Tropical or Jolt Pearl, or the Blue/Green Centaur would let you move back right a little and still give you plenty of hit.
