I have a bass currently stung with Helicore med. pizz strings, and I REALLY like the slightly looser feel....I'm thinking about some Spiros, but on the tension chart in the sticky thread at the top of the strings forum, the Helicores sit in the middle between Weich and Mittels. I LOVE mittels, but having come off of a hand surgery, I don't want to hurt myself using a higher tension string than what I am currently playing, but I love the Spiro sound! How is the tension on the Jazzers? Anyone throw me a bone on a string that sounds like Spiros, but have less tension, but more than Weichs? Or...I am slowly slipping into a state of Stringitis, and am hoping the mythical unicorn is out there, somewhere, waiting for me?
