thanks all. i am definetly very happy with the D'addario chrome flats (light gauge, medium scale) on the JS bass- both my previous JS 1 w humbucker, and my current 1970 JS 2 w Bisonic & mini humbucker. the Bisonic though has got me wanting to try the TI flats on the JS, as those are definetly the way to go for a Bisonic Starfire (imo). I have not played or heard TI flats on any Guildbucker equipped Starfire or JS bass, but the D'addario chrome flats sound wonderful on those.
Again my current JS bass has a Hagstrom Bisonic in the neck and Hagstrom mini-hum in the bridge. I could easily stick with the D'addarios, it sounds fantastic, to my ears. but knowing how the Starfire sounds im tempted to "go there". right now with only the Bisonic pickup engaged (neck) it seems to spit out certain notes as Starfire tones and other notes as Guildbucker tones. shes kind of lost, ive almost felt from the beginning like "the pickup wants out" and would be better served inside a hollow/Starfire bass...but i'm not about to do that, on several levels, so might try the TI's and see how it goes. as long as the tension is no different than on a Hobken SF bass it sounds like something I should try. based on Happy Face's reply and the info from the rest of you I think it's worth trying them.
