I've got some breezes as well and although I haven't taken them out yet (JUST got them in the mail) I tried it out and that thing is flippin' toasty! I love it, also makes a great blanket! I also got 1oz overstuff, and Mike made it out of M50 for me so it'll resist the wind a little bit better than regular nylon. Going to bring it through the ringer this year, see how it does in the low temps.
But it all really depends on what kind of coverage you're looking for. Mike at te-wa unfortunately doesn't do full length breezes, though he MAY if you ask nicely. WL already makes a SS full length, something to consider. Can't go wrong either way!
