I normally use Ernie Ball 'extra slinky' strings on my standard guitars, and was so glad to finally find double-ball strings of the same gauge for my Steinberger! Before now, I never could find what I wanted - I'd end up having to settle for thicker strings, making it more difficult for me to play (I have small 'girl' hands!). These cost a bit more, but that's to be expected for 'non-standard' guitars, and they have a nice feel to them as well. My strings of choice for headless guitars!
