I saw the pictures- I've used these studs too, but used 2x3 blocks,
like i'd seen framers do, in corners for stablity.
You didn't and had good torsional strength? That's great news because
one drawback to steel studs for me was the extra cutting of the corner
blocks. Another was the sharp edges. But on the whole is this a
technique you would use again?
