Holy Carp! That must be an expensive system.
Price aside, can you tell me why you went with the Karver blocks instead of, say, a floating Harken 2651 40mm Ti-Lite Single, a Ronstan 20151A or 30151A cheek block forward, and a smaller diameter secondary line? That's what I've been thinking of using.
Of course, we all wonder what blocks you use in the aft end.
Are you using a boom-external outhaul with this setup?
Thanks for the pics!
