Ok, I've been reading the string threads for the past hour and I'm still not any closer to an answer. Here's my situation. I've got an $1800 chinese plywood bass (a Samuel Shen I think, the luthier put his own lable in it and is evasive about the actual maker), that is the nicest plywood bass I've played in my limited experience, but is still just a plywood bass. I've been using Spiro Weichs on it after taking off the original Helicore Hybrids because they just sounded dull on this bass. I'm pretty happy with the sound of the Spiros, especially the nice sustain, though the E string is a little weak (but hey, you get what you pay for in a bass). The only problem is that my arthritic hands would really appreciate a little lower tension, though I don't want to sacrifice too much in terms of tone and sustain. BTW, I'm mostly working on pizz jazz, but am also learning some arco, so arco response is also a consideration. After reading a lot of the threads here, I'm thinking about Spiro Solos tuned down to orchestra pitch (though I'm concerned that they may be *too* loose), Obligatos, or possibly Superflexibles. I get the impression that most of you have much better basses than mine, so I'm asking for your opinions, but keeping in mind that I'm dealing with a plywood bass and it's inherent limitations. In a nutshell, what I'm looking for is tone and sustain similar to the Spiros, less tension, good pizz and decent arco response, and a little stronger E string response, all from a plywood bass. Not asking for much, am I....? I can't afford to try several different sets to get what I want, so any advice and opinions would be greatly appreciated.
