Amsteel could be used, but it might slip in the clutches, as the line is very slick. Dynex Dux is designed for standing rigging and has no place in running rigging, and is specifically heat-treated to help reduce creep.

Do you have dacron sails? If so, then going with T-900 or another spectra/dyneema-cored line might be overkill for your sheets. You could use it for the halyards to minimize weight aloft and give you more of a safety margin on the halyards.

Cajun Trading Company has pre-packaged halyard/sheet kits for many common boats at a pretty good price. The kit for the Catalina 30 looks like this:



That kit is using XLE, which is their version of a polyester double braid, similar to StaSet, which is not a low-stretch line by any means.

Using a light dyneema/spectra-cored line for the spinnaker sheets or genny sheets makes sense, since a lighter line would help the sail keep its shape better in light air conditions. Spectra and its cousin Dyneema don't absorb water and are lighter/stronger than polyester.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
