Bill,
Jake has the right set up. The wire is probably better for overall adjustments, but it really is hard on the legs of the crew. However, instead of wire, you can use non-stretch line that will be lot more forgiving.., and still give you the ability to test different jib cleat settings.

However, on my Taipan I have the loops. <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />
