Nice, I just bought myself 2 Super Capacitors for $18 bucks + P&P

This seems to be pretty high impedance:

"v=Nominal impedance: AC 10 megaOhms, DC 14 megaOhms"

A better indication of what these parts can do is their ESR.

See these articles, which indicate a low ESR cap is needed.

This link to a 150F 2.7V cap at digikey is for a part with 14mOhm (milli-ohm)
which indicates how fast you charge up the cap and also how fast it can discharge.
