I have a Scott addict frameset and plan to press fit the headset. Should I use a little grease 'between' the headset cups on the inside of the carbon headtube? FSA - (it is a fsa headset) say to use grease, but according to what I have read, some say not to - it is 'rumoured that Scott say not to. I have tried to contact Scott themselves and checked all their 'manuals' but to no avail.

    Try Vaseline - it will help with fitting but won't have any effect on the materials. Some manufacturers suggest not using grease on bare barbon.
    Make mine an Italian, with Campagnolo on the side..

    Cane Creek seem to suggest using grease for the crown race and bearing cups during assembly ... ctions.pdf

    Don't know if this helps but my gut feeling would be that using a small amount to aid assembly can't do too much damage

    Scott say no, but I used some when fitting the cups to my CR1-SL. It hasn't disintegrated yet.

    Looked like Scott used something green when pressing in the BB at the factory...

    Pretty sure I used carbon assembly paste.

    I've normally done them dry but I doubt you'll damage anything with grease. You could use assembly paste but the grittiness may make fitting harder.
