What could be a more opinionated discussion than strings - motor oil? Fender vs. Gibson? Or perhaps the best bass for metal? 
Ok, to be serious, I played a Cirrus for 6 years and put either Peavey Cirrus strings on it or DR's (when my local shop didn't carry them any more). I used Hi Beams for a while and then switched to DDT's to try something different. Since my church sound guys (and pastor) prefer a bright, aggressive tone, dead strings (read: 3 mos. old) were unacceptable so they got replaced frequently. The DR's were nice and bright, but after an initial zingy period they gradually tapered off - even with regular cleaning.
For a couple years I owned a Dingwall Voodoo fiver and loved Sheldon's strings. After nine months of owning it I put on a new set and couldn't tell much difference - those strings lasted forever, credit the scale/tension and quality of the bass/strings.
My last fiver was a Jackson on which I put D'Addario ProSteels (they were cheaper than DR's, I didn't have the 35" scale length requirement of the Cirrus and the sound was decent enough not to require the extra $$ for the DR's). Still, had to change them frequently to keep 'em bright and get good enough sustain out of them.
My current bass is a custom five string which is shod with Circle-K's (.150 balanced set.) The bass already has great sustain, the larger strings add to it, and although the Bart pups/pre tend to emphasize the bottom end I just boost the upper mids and highs to get the tone I need. The strings don't get harsh like SS can be, and they last a reeeeely long time. I'm at five months on my current set - and don't play any less than before; sometime next month or after the new year I'll order a new set.
What quality I really like is the fact that my tone changes less over time and is only perceptible when I change out the strings. I use denatured alcohol to clean them regularly and that also helps; and an older Circle-K string has the flexibility of a new D'Addario - if not more, even after months of use.
Either way, have fun on your quest. BTW I run Amsoil in my van...
