Warping lumber is definitely a headache, and your frustration is understandable. Engineered lumber like LVLs can indeed help, but as you mentioned, the cost-benefit ratio isn't always favorable for smaller projects. I've found that careful storage—keeping lumber stacked flat and covered until use—can mitigate some warping issues. Still, wood's unpredictability means there's always a bit of luck involved... even with the best precautions.
Totally agree on the storage point—keeping lumber flat and dry definitely helps. Another thing I've noticed is that selecting straighter boards at the lumberyard can save a lot of headaches later. I usually sight down each board before buying, even if it takes extra time. Still, sometimes you just get unlucky... wood has a mind of its own. For critical walls, I've occasionally resorted to metal studs—they're straight every time, though not everyone's cup of tea.
Metal studs are reliable for straightness, true, but they can feel a bit clinical in residential spaces. I've found that carefully choosing kiln-dried lumber and letting it acclimate indoors for a few days before installation helps minimize warping issues. Still, as you said, wood is unpredictable—sometimes despite best efforts, you'll get a board that twists overnight. For critical walls or feature areas, engineered lumber like LVL studs can be a good compromise: straighter than standard lumber but warmer than metal.
I've had decent luck with LVLs too—definitely straighter than typical lumber without that cold, industrial feel. But they're pricier, so I usually save them for walls that really matter, like kitchen backsplashes or tile showers. Still, wood seems to have a sense of humor...you can baby it all you want, and it'll still surprise you occasionally. Guess that's part of the charm (and frustration) of working with natural materials.
I've found LVLs useful too, especially for critical areas like doorways or tiled surfaces. But even then, wood can surprise you—I once had an LVL twist slightly after installation. Nature keeps us humble, I suppose...
