I also use - and like - the TI Jazz Flats, but...
I only have them on one bass - out of 27. Why?
- I play a lot of music that they simply aren't particularly well-suited for. I need "Old School Thump" a lot of the time - which is something that TIJF's just don't do very well...
- TIJF's are famous for their harmonic overtones. I have a bass that, for what I play with it, really needs those overtones. Which is why it wears TIJF's. But, for most of what I play? Don't really need those harmonics - so those basses wear something else...
- TIJF's are also famous (or infamous) for their flexibility. I've been playing basses with flats - mostly pretty stiff flats - with a pick for 50+ years, now. It's hard, and time consuming, for me to adapt my playing style to play TI's with a pick. I
can, but... why bother? The only bass I own with TIJF's on it, gets used for music that's not well suited for playing with a pick anyway, so... no problem.
So... for me? TI Jazz Flats are pretty much One Trick Pony strings. But, for that one trick? I can't really think of a better string to use...
