I bought a 5 string set of DM Blue Steel light nickels three weeks ago.. I something aroung 40 or 45 bucks for them.. When I put them on.. they seemed to worth the money I paid for them.. I had never paid so much for a single set of strings.. They are almost death now, their bright faded away as fast as any other set I've gotten for less than half of what I paid for the Blue Steels.. That just sucks! I didn't even played them too much.. I walways wash my hands before playing and I very rarely sweat.. Is it common for this strings fo die so fast? Why are they so damn expensive?
