I really like the Fender 7120s which I tried on a whim when I was visiting San Diego and got a pack cheap at Blue Guitar. if they made a 5-string set for the 7120 or a 9120 I'd try to stay with the Fender black tapes, but that doesn't seem to be the case. so . . . Labella 760N5 vs. the GHS 3060 or Rotosound RS88 nylon tapewound B strings -- ( or any others ? ) -- has anyone tried any of these five string sets and if so how do you like the B string ?
