I understand what you mean. When I first knit with a circular, I couldn't imagine that the stitches would even be the right size.
The needles come coiled in the package, and unless you straighten them out somehow, they'll sproing back up on you, especially if your knitting flat. If you're knitting in the round, the weight of your knitting will eventually take over.
Maybe you can start a trend--fishing weight stitch markers.
