Optiweb 19077 Light/Heavy : And just when I tought I have seen it all..

I tried these strings on one of my guitars and after a week I noticed that the sound stayed as crisp as when they were changed! And it stayed like that for at least two months of daily playing!

And it definitely feels much smother than other strings...

When I took the guitar for a professional setup and forgot to send along a set of these (the guitar shop does not stock elixir) they put in another well-known brand. After just a few days I had to replace them with a new elixir set as the sound was getting noticeably duller and duller every day. Not only that but the collection of dirt behind the strings that I took for granted for as long as I remember, seems to be gone with these strings - don't ask me where it goes...
