Yes, the TI Jazz Rounds are outstanding and truly unique. They're one of the best electric bass strings ever made IMO. I'm still a bit wary about recommending them to others because the TIJRs are so different from any other strings. I suspect a large percentage of bass players won't like them due to the extreme flexibility and ultra-low tension. These strings will not only require a very different setup, they will probably also need you to adapt your style of playing.
If you're willing to do this the TIJRs are in a class of their own. Yes, GLORIOUS is a good way of describing them. The amazing thing about them is that even with their incredible flexibility and ultra-low tension they are perfectly capable of holding a steady pitch. They don't go BOOooiiIIING like many other low tension strings. Even the short scale sets are great! They are also far less prone to buzzing than I would have suspected from such light tension/gauges. Your bass needs to be in good shape though and the setup needs to be perfect. Any issue with the neck/frets will definitely come to the surface with the TI Jazz Rounds. Even the TI Jazz Flats feel stiff by comparison!
I'm not sure TIJRs are the right choice if GHS Round Core Boomers are too dark though. At least not compared to a relatively fresh set of RC Boomers. The Boomers will be much brighter out of the box. Of course the RC Boomers go dead relatively fast whereas the TIJRs just mellow out very slightly and then seem to live forever so in the long term the TIs will definitely stay brighter and fresher but they will have no metallic "zing" whatsoever, just a nice upper mid presence. A warm, organic tone with superb clarity and a kinda "orchestral" vibe is what the TIJFs are all about.
