I generally use Elixir coated strings, but it was hard to find 11-54 Elixirs.
It felt very good out of the package, and several days after putting them on my guitar. Not as smooth as Elixirs, but still quite smooth. They felt too premium to feel like non coated strings, but less "coat-y" than Elixir ; which, can be a good compromise.
However, after 2 weeks, they started to lose their smoothness, and started to feel like regular strings.
They also started to corrode a tiny bit few weeks later.
But still good sound and feel, very resistant.
