Coilgun Question?

If I wish to put the maximum amount of current possible through a coilgun coil in the least amount of time, is it best to use a multitude of tiny capacitors , all in paralell, charged to a high voltage (330v)and wired to a small-wire coil or a single HUGE (1-Farad) capacitor charged to 10v and run through a large coil? ume the big cap has 40 Ohms internal resistance.
