I absolutely LOVE Thomastik Infeld Jazz Flats on my 4 string basses. But I was pretty let down by the low B in their five string set. I’ve also got a 5’er setup C-E and felt the high C lost its edge rather quickly. Anybody else have a similar experience with Thomastik Infeld JF34s in 5 string basses?
 
Do you have a bass that you’ve setup like this? I’d be interested in hearing how you think the Cobalt B differs from the TI? I had Cobalts on a Dolphin a few years back. They seemed decent enough, but it’s been a while.

9050L with 130B Cobalt flat on my friend's Ibby SR305E.

I recommend 130B Cobalt mix Ti flat due to both have rough string surface texture compare to Group flat 2810's smoother surface 130B.
 
I've only used the TIJF 5-string set with regular tuning and it's actually one of very few 5-string sets I enjoy playing. With most other 5-string sets I don't like the radically different timbre of the B-string. The transition from E to B is much smoother with the TIs than with most other 5-string sets.

With alternative tunings... not a lot of gauges to choose from with TI so if they don't work for you it's probably time to look elsewhere.
 
Probably not your issue, but ... is it possible you just have a bad string? I've been using the TIJF 6-string set on my ABGs for years, and the low B has been great for me. I did get a bad low B once, though. Fortunately, the US distributor, whose name and address I can no longer recall, replaced it free of charge, and since then it's been smooth sailing.
