It seems that the CG lever problem occurs but not in every watch. I'll add to the experiences though and mention that mine, while straight, isn't necessarily 100% flush. It pokes out just a little bit (~0.3mm), not enough to tell from a distance, but if you run your finger across it you'll be able to tell.
Your best bet would be to gauge the QC pictures and ask for specific pictures detailing the shape of the CG to make sure you get a nice one. Good luck!
