Kk Just got done with my session while trying this setup.
I didn't see any difference in the smoke
The ONLY difference I saw was that the moment I put on the coals, some smoke from the glycerin on the foil started to sizzle and some smoke came from the holes in the foil. And that the very first puff had a thin but more smoke compared to if I didn't do this setup (no taste in those first fews puffs).
When the smoke started to get to its full potential, I didn't see any difference.
