 The helicoid grease turned up today and the lens has been scrubbed spotless and regreased - a lot of the friction was coming not from the helicoids but from where the front assembly is mounted, 2 parts rotate against each other with a couple of brass shims in between. Cleaning and greasing them has made all the difference.

Not exactly super easy to turn but much better, butter out of the fridge!

I have also acquired a 2x macro teleconverter and its action is similar, so I have obviously been spoilt by almost frictionless AF lenses!
