Bomb300,
The first impression I get is that you might need to fill the hole between the goliath and the time zone. Any of the balls you mentioned would fit into this niche, it would just depend on what reaction you are looking for.
If you want a bit more skid/snap ( like the time zone ), then the intense might be what you want. If you want more of a roll/arc ( like the goliath ), then the impulse or the absolute would fit better.
The impulse is activator with a light load particle, the intense is activator plus with a higher rg, and I've been told that the new absolute is activator plus with a lower rg core( original inferno I think ) and a ruff buff finish.
You might want to consider the classic zone also. Activator cover with an assymetrical core similar to the impulse zone.

You must face it.
