Yeah, i've been collecting more info on this.
For AWG24 at least, it looks like ~11 strands is your typical stuff and ~40 is the ultra floppy stuff.
There's lots of alibaba sellers for silicone ~40 strand awg24 wire but the ~11 stuff is less common.
I used to buy it from digikey, but at NZ$80 for 150m i cant really justify that when silicone wire is ~NZ$50 for 400m on alibaba
