What size Dyneema?

Quick question, I need to order some running rigging line for my next RG project.
What size do you use?
I am thinking 4 or 5 mm.

Hi Kurt
I’ve been using 30lb Dyneema from P J Sails ( http://www.pjsails.co.uk/cordwire.PDF ) for the past few years on my RG65s, Micro Magic and Footys. It runs freely and is plenty strong enough even though it seems very thin.
Cheers
