Spent the last two days with this setup. No discernible hit to taste at all, didn't know what to really expect because I had the decarb kit installed as a whole before and could tell the difference taste wise, so this was a welcome outcome. And as for the cloud difference I see it, not huge, but you see it and feel it, especially with third and fourth and beyond draws.
I've noticed I've coughed more times with this configuration at pink temp and my typical glass straw setup than before, which is fine, buzz wise and the fact that the vapor temp doesn't feel any hotter.
I'll probably stick with this heater core configuration.
