Wanted to let you know that after much searching and trial of lots of medium-light gauge strings, these medium Elixir's work great on my $50 mandolin. I've always been leery to put heavier than the 10-34's that came on it 4 yrs ago, because people warn against it and when stringing it up, with even lights, it seemed like mucho tension. I made a set of: 10,16,26, 38, without any increase stress on the neck. But these were not coated and they still didn't have the tone and speed of heavier strings. Took my chances with these 11, 15, 26, 40's. There was no added movement of the neck and intonation and action were the same as the with the medium-light sets (So Cal. weather). Use lots of Elixirs on guitars we have, fantastic strings. I was using light Elixirs on the mandolin but glad so far, about a month, it's working out to use mediums, (speed, tone, finesse). Wipe them down, ax in the case, they'll last a long time. I also use a $35. pick. Cheers.
