I have owned and played several basses in my life and none have played as nice as my Musicman HH 5 string stingray the b string is perfect to me.
I will say that i played a lakalnd 55-02 once and that B string was awesome also!!!!
I'd say the nicest 34" 5 strings I've played have been Sadowsky NYC 5s... The nicest playing 35" 5 string I've played was my old Ken Lawrence. Sigh.
