Hey Dieter,
Generally the recommendation is to use a clutch where the line is in the upper range of the size... So a 6-10mm clutch works best with 10mm line. With really highly loaded lines like racing halyards the only thing I have seen that really works is a double clutch. Where the line runs through both of them. If you go look at Lesson #1 they use this on the main halyard.
Downside is you have two clutches. Upside is you can ease the line simply by working the clutches.
