I would think stay-stitching would actually distort triangles if you are stay-stitching on the bias edge!
I was thinking the same thing. I'm working on a quilt now with lots of bias edges and I'm about ready to pull my hair out because of all the distorted blocks I have. I wouldn't do anything that might make it worse. I used sizing but next time I will use starch and see if that helps.
