When I got my first Ibanez SRF706, it came with D'Addario Chromes, right from the factory. They sounded great, and felt pretty comfortable, too. Then, the preamp went fuutt! I returned it, and wound up buying a used one on Reverb, which came with DR Sunbeams. I like these even better...very articulate, lots of positive fretboard interaction, and very smooth feel for roundwounds. I'm keeping those on. And just for the record, my fretless Jazz bass has had roundwounds on it for about 30 years...there are some light lines from the strings, but really nothing that affects anything. I might get the neck planed...in another 30 years or so.
