[quote=davefarmer]I think most of us are using 5/16" (8mm) or 3/8" for the mainsheet, smaller runs smoother thru multiple purchase blocks, and is harder on your hands, bigger is more comfortable, but runs a little slower. 5/16" is probably fine for your jib sheet, as the load you're applying is not large. And I doubt a dyneema or vectran cored line is very important for the jibsheet, more so for the mainsheet. You could also check riggingonly.com and sailcare.com for slightly better pricing, although more limited selection than say apsltd.com.[/quote]
