Sorry but I love them, cant get enough of them. Especially on the Rainsong OM10.

Mind you, cheap & cheerful Martins on the Yamaha APX6-12 and the Jim Harley give the same sound as when I use Elixir. But the Rainsong is wonderful as the take the bright edge off.

The technical details talk of certain harmonics being damped through the smooth outer profile of the strings. Mmmm. We all have a specialised subject and mine just happens to be mechanical vibration, even wrote my PhD thesis on the subject. Let's just leave it as "I would love to explore the reasoning and evidence for this to be a practical as opposed to theoretical advantage."

Talking of practical, they should for most of us last longer than most other strings and indeed they do. One good reason for considering them, despite the higher than average price.
