I put a set of Chromes on my Lull P-5 tonight, replacing the TI JFs that I was using. The TIs were my first serious experiment with flats, but reading Sundogue's posts made me think I'd perfer the Chromes. So far I have only played through headphones with my PJB Bass Buddy, but I'm liking the Chromes so far.
This is the .045 .065 .080 .100 .132 Long Scale set, which was my only 5-string option at GC. I kind of wish the tension was a bit higher, but it's certainly higher than the TIs. (Maybe I need to try the Labellas eventually.) I can't recall if it has been mentioned in this thread, but these strings take a little extra work to put on a 35" scale bass. (There is a Super Long Scale set I see on juststrings.com, so maybe that's what I needed.) I had to trim about 8mm of silk wrapping off of each string to get it past the nut. It worked, but was a bit of a pain. And it leaves some messy frazzled silk up there which might bother the OCD crowd. I think I'll get over it.
It's amazing how bright these are when brand new. I'll probably like them better when they've faded a bit, but it's also kind of cool. You could even slap on these I think...
I'll have more to say once I've heard them with the full band (on Monday) but I will have to go to the rehearsal space on my own tomorrow and see how they sound through my full rig: Demeter VTBP-201, Aggie DB 728, Berg NV215.

They definitely have a different tonal balance from the TIs. The most positive difference for me is that they don't have as much of that nasal ~800Hz "honk" as I was getting with the TIs. I also seem to hear the added girth on the D and G strings that Sundogue mentioned, but I'll have to hear them with the full band to be sure about that.
