Best coil? GT40R, or SU12R?

Awww guys, this has to be one of the nicest offers EVER. But i've already received my Bosch GT40R, $42 AUD to my door.

Granted, if it doesn't do 'tha job' then i'll be coming back to ya to see if the offer stands.

So i've got replacement dizzy rotor, points set, coil and cap. already got the 9mm spark leads. This should get me back up and running!

(RRR - 60K volts is gonna get up ANYONE's jimmies! :burnout:)
