Rick, The "fuzzy Dacron sheets" sold by Cajun Trading is actually Novabraid XLE-Z Feel, which is made from a spun polyester fiber to get softer hand. I agree that 3/8" is probably a better size for her sheets and should match the size to the jaws of the self trailer. I would argue that Stretch in any sheet or halyard is generally not a great idea. Much better to ease sheets before a puff hits. If stretch was good, we'd all be using nylon sheets.
If Sophia is using winches to sheet in her Genoa, a single braid will flatten out on the winch drum and wear prematurely, plus there is really no benefit to having a floating jib sheet (other than lighter weight in super light air conditions). Yale Ph.D.makes a great main sheet since it runs really well in blocks but does not float. And the reason it is made with Dyneema is to reduce elongation but being a single braid, it doesn't stay round under load. Getting a line that has good grip in the winch, low torsion to reduce hockling, twists, and birds nests in the cockpit is far more critical when choosing a construction. The best size line to use in the Genoa car traveler should be a size to fit the sheaves on the traveller assuring a safe bend ratio but not exceed the sheave width, allowing the line to run without chafe. If the traveller uses 50mm sheaves, 1/4" line is the largest line you should use to assure a 8x ratio. Larger line may not grip in the cam cleat that controls the line. Buying oversized rope to improve grip on a line that is rarely handled is a waste of money however, the loads on a Genoa car control line can be high if you are adjusting car position under load, so this may be a good application for your PHd single braid line, which feels soft but has lower stretch.
