Patrick — I basically replaced two blocks, each with a roughly 90-degree lead (at the mast/boom gooseneck, and at the mast partners), with a single block with about a 150-degree lead at the deck collar. With enough purchase at the boom for the sheet (in my case, 4:1), I just need to overcome the friction of that one acute lead.
