Sure. I'll try to sum it up w/o derailing the original topic here. Feel-wise, they're different. La Bella 760FLs have a glassy surface and have more tension and less flexibility. You can kinda feel the string thumping when you pluck it. A lot of guys describe TIs as spaghetti feeling. I think this description is a little over the top, but they are the bounciest feeling flats I've played (they feel a slightly more flexible than a standard gauge of DR Sunbeams under my hands.) They play more like rounds than flats. I like the texture of the TIs better too. They have more of a smooth matte finish when broken in.
Now as far as sound goes: as you can hear in that sound clip, the TIs clearly sound like flats. They have more sustain than the La Bellas, but less attack/thud. The TIs have sort of a receded attack, which I presume is due to the unique silk inlay found in their strings (that inlay also reduces highs/harmonics). You get a good little midbass bump w the TIs, but there's not a lot of deep low end or extended highs. The La Bellas have both the deep bass and clicky highs. I can tell the difference between these strings in or out of the mix bc both have been my go-tos at certain points, and I've recorded and compared them. Like a lot of TI fans say, the TIs just sit in the mix. There are no extraneous freqs w the TIs, just the ones that matter in a mix.
Having said all this, these differences may or may not be night and day for some people. I definitely wouldn't say 760FLs and TIs are similar strings at all relative to other flats. I guess maybe my point was that some sets of flats, when broken in, can sound more similar than one might expect.
