Things I'm pondering about my stays

I'm avoiding working on pondering things about my stays. 

1. Cording vs boning on the back edges. I know cording is period and all but as an apple shaped girl if I don't have something to keep it straight sometimes my rolls eat things so to speak. It'll just get all bunched in at the waist. So I was thinking about boning those edges. 

2. Eyelets, hand sewn or metal. I know handsewn is period but frankly I have very limited faith that these are even going to fit. Yeah a did a muslin...but without being really finished it's so hard to tell. The bust gores LOOK to small when I hold them up to myself, but they don't go as high as a bra, are meant to push up, and holding them up over a fleece, a sweatshirt and a modern bra probably isn't helping me. 

3. A busk. Paint stir stick or wooden ruler? Wish I had something in the house that didn't require a trip to go get.
