Been playing a while now and I started with a 5 string bass with a low B, so i'm not a 5 string noob. I see a lot of guys going bigger in the B string world .135 plus. I've tried a .135 one time and it was HUGE to me. I've been using a .130 for a while now but I'm just not satisfied with the tone of the string as I have been with a smaller B string (.125). I've used three different brands with a .130 and none of them satisfy me as much as the tone of a smaller string. Why is this? it's only .05 of a difference.
