OK next corner of the Spinny, I have used D12 as the halyard, it is soft and relatively easy on the hands, you can create alsorts of nice knots and the best bit, it doesn't burn the spinny like other halyards will when you don't quite get the snuffing bit right.

So what about using 3mm D12 for the sheet and put a cover or covers over it to bulk things up bit where we are handling it, some of the dedicated sheets are bulky heavy and least desirable, expensive. Any body been there done that ?
