"perhaps investing in better drying practices or sourcing higher-quality kiln-dried lumber upfront might be more effective overall."
Good point about the drying practices—it's surprising how often that's overlooked. Have you checked your moisture content before installation? Even kiln-dried lumber can vary quite a bit depending on storage conditions. I've found that keeping lumber stacked and stickered properly on-site for a week or two before framing can really help minimize warping down the line. Might be worth trying if you haven't already...
Checking moisture content is definitely key, but sometimes even with careful stacking, I've had lumber twist on me. One thing I've found helpful is to frame walls in smaller sections rather than one long run. It gives you a chance to correct minor bows or twists as you go, instead of fighting a big warped wall later. A bit more tedious, sure, but it saves headaches down the road...
"One thing I've found helpful is to frame walls in smaller sections rather than one long run."
That's a smart workaround... but I'm curious, have you noticed if certain lumber species or grades twist more than others? Wondering if material choice could make a difference too.
I've definitely noticed differences depending on the lumber I pick up. For instance, standard spruce-pine-fir (SPF) studs from the big box stores can be hit or miss—I've had batches that twist like crazy after just a day or two onsite. On the other hand, Douglas fir or southern yellow pine seem to hold their shape better, at least in my experience. They do cost a bit more, but if you're fighting to keep walls straight, it might be worth it.
Also, moisture content plays a huge role. Even good lumber can warp if it's stored improperly or gets wet. Ever tried checking moisture levels before framing? I've started doing that occasionally and it's surprising how much variation there is even within the same stack of lumber...

That's a great point about moisture content. I've seen perfectly straight studs warp overnight because they were stacked on damp concrete floors or exposed to humidity swings. One trick I've used is stacking lumber off the ground on scrap 2x4s or pallets, with spacers between layers for airflow. It doesn't eliminate all warping, but definitely helps keep things straighter until framing day rolls around.
