Thanks for the advice. I didn't manage to get the old stuck spring off so had to go to someone with the know - how and tools.
However the new Arnott gen 3 springs are a revelation. Roll is significantly reduced with only marginal increase in bump thump. I'm now looking at dampers and think I will go with soft ones as I don't need them to be too stiff.
