{} I have 5 packs of Super Bright Steel Strings. These are .45 .65 .85 .105 (boxed) + .130 (single). Normally the 5 string sets come with a .125 B string unless you buy a 6 string set that includes a .130. I just ordered and received these and love the zing of them but I drop 1 full step and 1 1/2 step down and these are a bit too flimsy for drop. Std and 1/2 step is perfect tension. So you basically get a full 5 string set with the .130 as the B string. The .130 B string is tighter than the .125 as I found it a little flimsy. $20 per set shipped in CONUS Lower48.
