When I bought my current boat it had a 16 year old Dyneema backstay, and the PO offered to buy a new backstay as he thought it was time.. It probably would have lasted much longer, as it had an intact black cover, but it was replaced anyways. It was made by BSI and purchased through The Rigging Co, on Edgewood road, Annapolis. Definitely more than half the weight of rod - I don't really think I would notice the difference if I had put a rod backstay on.
