I replaced the stock strings on my CR5M with a set of Pirastro Obligato's and really like them. However, I still have the stock B string and it has to go!
I'm strictly a pizz player so bowing isn't a concern at all. I just want to woodiest, growliest, meanest, (etc.) B string I can get. Should I just go with an Obligato B or what? I realize this is HIGHLY subjective but I'd like to get as much input as possible since this one string is probably going to cost in the neighborhood of $70

.
I hardly ever use the magnetic pickups so either steel or nylon core is acceptable.
Thanks!
