What capacitors would be better for a coilgun? Answered

I have two sets of capacitors i could use for my first coilgun, and i was wondering which set would be better and why?

(2200uF - 16 volt) <---- Old computer cap.
or
(120uF - 330 volt) <---- Regular camera cap.

More volts, less microfarads (uF) means you'll get a very fast surge of current which will suck the projectile down the tube without reaching past center. You want it to cut out before it hits the center.

As it is, your 330 volt caps would be your best bet.

So does the uF actually affect how well my coilgun works? And if the photoflash caps are better would that mean the higher the voltage on the caps the better?
