I have played the old version of Elixir Nanoweb strings a couple of years ago, but not the stainless steel version. They seemed to have quality problems with the coating, after quite a short time. These ones are more durable. Since March 2013 i play them on a Fender Jazz Bass. The coating is still in a good condition. The sound is superb. I prefer it over the nickel ones, because of nicer overtones. I like it a lot. You need to spend a lot of money, but you get what you pay for. Here you get long lasting strings. Go for it.
