My vote went to roundwound nickel. After trying way too many different strings over the last year and a half, I've settled on Fodera Diamond Series guages .45 - .130. These are by far the best I've used, and I'll keep using them as long as I can get them (they are hard to come by here in Norway, so I usually have to order direct from Fodera).
Thanks, guys, keep em coming. FYI I did search the forums for "strings used on sr5 and MM" and surprisingly enough, they all discuss what strings people use on the sr5. But little mention of what kind of sound they like, so there's lots of what, but no why. Figured I'd focus the discussion to what exactly I'm looking to achieve.
I use the strings that the masters of MM elected to put on the bass at the factory.

They are very bright and punchy, which is an excellent compliment to the super low end that the pickups in the MM-SR5 bass can deliver. Those two factors provide the (kick in the nuts) that I want to deliver everytime I play.
As far as the sound l like...I play in 2 bands, plus I am working on a solo project, each of them requires a different sound. from very deep and clean jazz, to bright and shiny trash funk, or grungy rock and roll.
With the SR5, and my Ampeg Stack, I can get every one of those tones.
Oh yeah, if you slap your bass like it owes you money, these stings are perfect..Nice and bouncy like

Can't recommend the TIs enough. They're nickel coated rounds. The MM sound still comes through, but in a more subtle way. For example wit the stock strings I get that ringing mid-treble grind throughout a song. With the TIs it only comes through in the quieter parts of the song, ideal for solos etc.
