i posted this question on th SOTW as well to see what they will come up with. in the end i decided to order Francouis Louis s size bare brass... few days ago it finally arrived! (it didn't take THAT long to arrive i just didn't order it right away). 🙂
does it fit? yes... kind of... not really... it's very tight, but usable. if you like to do the Dexter Gordon thing and pull it all the way back, welllll... there's no way you can do that. but upfront or middle position works ...ohhh, and it will scratch your mpc like crazy!!! so if esthetics are important to you, this ligature is not a good choice (i don't really care about that, so it's all good)
would i recommend it? no. well not unless it's your only option... it works, but i am sure there are better fitting things out there...
having said that, i was always a believer that ligatures have zero to very little influence on the sound (mostly material vs. metal just because it's hard to create same tightness or put them in the same position)... but the change with FL is quite noticeable, especially on my berg! as much as i dislike to use these terms to describe the sound, i would call this more open, more bright and strangely a bit more projective (--- usually i find that when things go bright they also get a bit thiner). maybe one day i will get a mic and record you a clip 🙂
i hope somebody finds this useful in the future and thanks again for help! 😉
