Thanks. I've decided to go ahead and upgrade. I'll go with a standard system with dual lines for each side of the boat rather than trying to design and construct something myself. In the end, I doubt I would save that much money and have it be as effective.

It won't have to have the highest purchase in the world and I don't have to worry about spin lines since my boat is equipped with a chute or Hooter. I only have barberhaulers, but I can easily work around them. They're not used much anyway except for downwind sailing.
