If you do a dropper like myself, afish, and many others here, as Heritage Angler says, one of the keys is length and diameter of the dropper. You wanna use thicker tippet and keep it short, or else it'll wrap around the main leader.

Also, nomatter how you do it, lots of shot and multiple flies significantly increases the likelihood of tangles. And not the unwrap type of tangles, we're talking the nasty, cut your line and rebuild type. To avoid this, don't go nuts on the casting. Open loops, just a flip really.
