I finally bit the bullet and decided to buy my first DB. I ordered a lefty Engelhardt ES-1 from a local luthier I met via Gollihur's links page. What kind of strings does Engelhardt use for the ES-1? I want to play pizz Jazz with a little arco classical (80/20). In looking at the various threads regarding strings, I am torn between Obligatos, Spirocores, Superflexibles, and D'Addario Hybrids. Any suggestions?
