"Dan, do you have a replacement in mind for your essence?"
I plan on making another cuben rain jacket shortly (I made one under 2oz and then sold it so I could make a nicer one, see MYOG section) that I'll carry on most trips where the weather looks good or okay. If the forecast calls for non-stop rain then I'll probably just use my 11oz North Face Venture Jkt or maybe I'll still use the cuben one. I plan on using the cuben one most of the time so I don't really need the Essence. I find the breathing of any WP/B jacket to be pretty insignficant when it's humid/raining so it's not worth carrying the extra 1/4 lbs.
I've got an eVent ski shell that I'll put the test this winter. I'm sure it'll be a little better, but I doubt it'll be so much better than I'd rather carry an 11oz eVent jkt over a 2oz cuben one..plus I trust cuben to stay waterproof more than I trust a PU membrane.
"I don't prefer the Essence – might sound trivial, but the side pockets on the Mica or similar are pretty important to me"
Interesting….I've tried on the Mica and my wife has one, but we both don't like these side pockets. When wearing a backpack, the hipbelt covers these pockets so you can't access them without taking off your hipbelt. That's why Marmot raised them up higher on the Super Mica. Conversely, the napoleon pocket is great for quick access to your camera, map or whatever. It's not a huge pocket, but it's super easy to access.
For lack of a better picture:
