I have been trying new strings again and knew Jeff Berlin uses these on his bass. I am quite impressed with them in standard tuning 100-40 w/130 B. They are more taught than any DR string which is good, some DR sets are to noodly for me. That being said they have that DR feel in a more taught string. make sense lol. I don't play metal or down tune at all, which is why I went on the light side. This concept is new to me but I think I like bigger core(s) in light gauge, slim pickings thou in terms of finding any other manufacturers selling them.
