Somebody will have to post a picture for you to fully understand what I'm trying to describe, a picture is worth a thousand words! There are a couple different ways you can do it, depending on which blocks/cletes you already have mounted on the front beam, you don't want to drill any more holes than you have to, so take a look at a picture or rigging diagram and see which way will work for the stuff you already have on the boat.

I prefer the two line setup, when I used the single line, it would always get twisted after a couple sets/take downs and it was much more drag trying to hoist the spin and pull the tack at the same time. Much less can go wrong with the two line setup, vs. the single line.
