Have you found the brazing specific fluxes easier to use?
Massively.
I know boric acid powder is super cheap but I found it pretty horrible to use.
Sifflux powder a lot nicer to apply, can be stubborn to remove if you’ve overlooked it.
Using Cycle Design Low Fuming Bronze paste now. Dunno about low fuming, it seems to be the smokiest! But it’s so nice to apply and washes off really easily too.
I’m still using Sifflux powder for dipping the rod into as I didn’t seem to pick much up when I dipped it into the paste.

Very helpful, thanks. I've just read the 'ask a framebuilder anything thread' and seen some more stuff some Coldharbour on using boric acid. I think I'll persist with this frame and lather loads on.
Made a start with gathering bits for the build, it'll look something like:
Chinese carbon fork/SLX double crankset/Sora R3000/9spd XT/Ritchey Venturemax drops/Novatec hubs w. WTB i25 rims/TRP Sypres + compressionless outers/WTB Ranger 2.25
If I find the frame fits me and doesn't drop to bits then I'll look at a hydraulic road drivetrain, likely Rival/Force 1.
Coincidentally the geometry looks pretty much identical to the frameset Konga Bikes are advertising on Insta.

Thanks! I did the DT/ST cutout by eye and it surprised me by how quick it actually was.
There's a very good chance I'm not, I'm struggling to get a decent consistency with the boric acid. I'll slap loads on the next joints. Have you found the brazing specific fluxes easier to use?
