appropriate for black powder upscale

[watermelonman]

Say you were building a gigantic version of a low power black powder rocket.

What would be the most appropriate propellant for a flight that was scale in spirit? White lightning, skidmark?

if you wanted a propellant that 'mimics' the appearance of a BP motor(smoke and flame) then a CTI classic propellant would seem to be the choice, if you just wanted the smoke (or are limited to AT motors) then the White lightning would make the best fit. sparkies are fun but they don't exactly do a good job of pretending to be BP .

depends on the size. Blue thunder in 29 mm sometimes looks like BP
