I normally use D'Addario EXL rounds, but picked up a set of their coated EXP strings on a lark. I stuck them on my SB5000, and so far they seem fine. Similar to the plain ol' nickle plated rounds, but perhaps a bit less zingy (which I was hoping for on this bass), and the feel of the strings surface is a bit more slick. So do these things actually last longer than the normal uncoated D'Addarios? I'll keep watch on how these do starting now, but I'm curious what everyone's experience has been. If they last twice as long for me, I might make a habbit of buying them. Otherwise, back to the good old EXLs.
