I run the tack line down thru a bow roller for the anchor and back to a bow cleat. A friend of mine has a setup similar to what you are talking about and it works too. I used to use our old symetrical chute the same way. Jibing is a piece of cake. If you really want to take the stress out of using a chute invest in a sock. Makes hoisting and shuting the chute down a cinch.
