Default KNO3+Sugar. Best measurements for...

What measurements have you all experimented with for the mixture that gives off the most smoke? Would slower burning also add to the smoke?

6/4 by weight. Slower burning mixtures dont always mean more smoke, but as long as the oxygen and fuel is well balanced, it usually doesnt matter, but for me slower burning mixes has a little more smoke.

The PFP database says to use 74.5:25.5, but I found that that left a lot of residue, so I started useing 3:2, which works fine.
