The thing that has kept me from buying the Crosstac is that I don't know how I would attach it to a backpack. With the Midway I can just roll it up and mount it on the bottom or top of my pack like a bedroll.

That said I have never actually used the Crosstac. If anyone has a good idea on how to attach it up comfortably I would be willing to try it. Looks like it is really well made.
