I love those basses, but I hate the feel of the strings. Earlier this year I visited Napoli, Italy and I went to Galli Strings. Together with Kala they developed a flatwound (roundwound too, if I'm right) steel string for the Kala with a nylon core. I took a set and I love it. it feels much more natural, less sticky and it's easier if you are used to flats.
