I'm using it so long, on Epiphone DR100 and Fender CD60 all mahogany.
Sounds like Leadbelly, Big Bill Broonzie, Robert Johnson, Brownie McGee...
Pros:
Natural, vintage sound
Easy to bend
Great slide tone
Hammer on and pull of are easy to preform and sound great
Great space for creativity
It keeps in tune very long
Long life strings
Cons:
Someone doesn't like blues, but those strings aren't only for blues
