Depends on your bass and what you like. I have some on my Ibanez and to be honest, they don't do the bass many favors. I also don't like the texture. The coating feels thick and doesn't really feel right to my fingers. They may work better on my fretless bass though if the Ebonol can handle it. Upside is they last for ages and look kickass, but if I wanted that dull a tone on my basses, I would just go for flatwound strings. Just my opinion.
