So I decided to start fooling around with my 5-string bass a few months ago, trying to make it into something unique. First thing I did was switch some strings around so it could be tuned in an open tuning, CGCGC. It was cool, but the strings on there have probably been on for two years (with the exception of a guitar string I used for the high C, that has been in the paxkaging for a year) since I haven't used the bass. 
So I'm wondering if there's anywhere that sells sets of bass strings intended for open tunings, or just individual strings. I know of Circle K strings (formerly Kalium strings, or something), but that's about it. Are those strings good, or are there better places for custom sets of strings?
Worst case scenario, I'll just get a normal pack of strings and tune them to where I want.
