green stuff

Have any of you used these pads, are they an improvement in any way?

I did try Green Stuff pads for a while on my road car, but found no real advantage.
I have found that std Fiat set-up in good condition works fine with good quality std pads (Mintex Ferodo etc.)
This road car is used for some Targa Rally events and sees some fairly hard use on occasion.
For my hillclimb car I use Uno turbo brakes but again on std 'good quality' pads the theory here being that on a hillclimb brakes do not get to heat up and must work well from 1st application.

If either car was being used for track days with extended periods of really heavy brake use I would consider something heavier duty than green stuff pads however ( though race type pads are useless on the public road.)
