So I've played bass for over 20 years, always used roundwounds, started with GHS in the early 90's, then Ernie Ball's and finally settled into Rotosound's Swing 66's (Love these, but they just don't seem to last for me! (Go dead fast)) Played some flatwounds on uprights, but I've never owned one. Always looked at the pack of Rotosound flatwounds when buying strings but at $70, it just wasn't worth trying. Went to another shop today, looking at a Jazz Blacktop (didn't buy) but found the "D'Addario Chomes" flatwounds for 35 bucks... Pulled the trigger, gave me an excuse to clean the neck on my J-bass anyways Just finished stringin' em up. I gotta say I wasn't expecting them to be as ringy as they are (which is good! I do love a bright tone) They don't 'zing' like rounds, but I rarely play with a pick anyways. They play amazing! Flying around the fretboard (I thought I'd encounter some more friction) with relative ease..we'll see if grime hinders this.. Can't wait to try it on my rig! Will have to wait until Friday.
