Aluminium radiator was for a few reasons...
Weight - yes, its lighter, but that wasn't the major reason. I think I weighed it, but can't remember the difference. Would only be 5kg's max I reckon.
Space - the Gondwana radiator is smaller in every dimension, but much more efficient. So smaller but better cooling. I needed room to relocate my steering reservoir, and to fit the oil cooler... but the main thing was that with the front axel pushed so far forward, and with high steer and the double ended ram full hydro steer, the top of the ram was mm's away from the bottom of the radiator. Now there is heaps of room and I can even reduce my bump stops (haven't done it yet, but it's on the list).
Power - no power sapping mechanical fan and viscous coupling to suck engine power... every little bit helps! I've seen figures of anywhere from 5-10% (tell em they're dreaming), to about 5HP improvement (closer to the mark I reckon).
Flexibility - I will wire a switch in that allows me to turn the fan off if I dunk into water ever again (not sure if it will ever see deep water or bog holes again... but who knows...)
TJ radiators suck arse - well, they do. I have replaced mine altogether once, and know alot of people who have over-heating problems. If they are damaged you can't fix them because they are plastic (on the ends). I have also replaced the viscous coupling once, and the water pump, etc...

at the moment I have a clogged up radiator and a viscous fan that is stuffed (so there is a temp one on the car)
