And the Winner Is
I finally got the three zippers I ordered last weekend and I decided on using the aluminum zipper. I did try to machine sew the zipper in, but it stretched out the knit placket too much, so I had to rip it out and sew it in by hand. I also sewed in some snaps to hold the placket down. I made the smallest size, but it's still roomy enough to add a couple of layers underneath. The Schulana Merino was a bit aplitty to knit with at times, but the finished fabric is dense and very soft. I'm really happy with how this jacket turned out!
