Im picky also and I made the switch... I really like how easy the stuff cleans up. T7 had a tendency to stick really hard to the barrel/breech. The BH normally comes off with just a wipe of a moist patch. As for smoking I would say its about 30-40% lighter than normal BP. As said above, it blows away really quick so you can see what you just shot at.

Its good stuff If I wasnt so picky, I'd still use T7, but I take every inch I can get
