So, are you saying with SUSY that renormalisation isn't needed?

Hi Rob,
SUSY doesn't eliminate the need for renormalization.
There are two types of divergences, logarithmic and quadratic divergences.
Renormalization handles logarithmic divergences quite well, quadratic divergences are a different story.
SUSY eliminates the quadratic divergences.
