Stephen, maybe this is not what you want but I just received an OR Maestro that cost me only $119 on a Campsaver.com sale a few weeks ago. Pretty awesome box baffled belay parka I have to say. My XL weighs in 700g and has ~4" loft at the shoulder. Size L is supposed to have 240g of fill, so a little more than my RAB Infinity Endurance(500g total) which lofts to only 3.5" at the shoulder.
But the Maestro is MUCH longer in the back, completely covering my butt whereas the Infinity is only hip length. Fully adjustable hood, double zip, with 2 nice large mesh stash pockets and a big zip pocket on the back that also serves as the stuff sack and makes for a nice pillow too.
I have only seen the Japan model of the Peak XV and frankly was less than impressed with its loft, though I did not actually measure it. Seems unlikely to have 11oz of down fill. I went to the EB store here in Texas yesterday to compare but no stock unfortunately.
