i've got a home made reverse flow offset stickburner and pretty much exclusively use kiln dried hickory splits. I don't foil anything unless I'm wrapping to hold in a cooler or cambro. To me its all about air flow & controlling the fire and, of course a high quality wood. I like to run a pretty hot fire to get a good clean blue/clear smoke and I really pay attention to minimize that nasty white stuff, especially when adding wood. If I need more or less heat I adjust the size of the fire, but try to keep even a small fire burning hot. I find the combination of a smaller hotter fire works with my rig and I can easily do long cooks if necessary without over smoking. More recently I've been cooking hotter & faster and as long as I pay attention to managing the fire I dont' have any problem with to much smoke.
