This year, I'm thinking of switching from a mummy style back (Western Mountaineering Summerlite) to a quilt, such as the Katabatic Gear Alsek

or a Z-packs hoodless bag

Such bags, would of course, require a hood of some sort.
Right now, I'm looking at upgrading my upper body layering system for 3-season backpacking by integrating a down jacket. The Mountain Hardwear Ghost Whisperer is at the top of my list. Looks like it comes in around 7 oz. Got good reviews here:

The question is: Do I want the version with a hood or hoodless? Would a hoodless jacket be more versatile? I would end up having a buy a down balaclava of some sort, such as the one GooseFeet makes for Zpacks:

This one weighs in at 1.3 oz. The thing, it's going to look a bit funky and be mismatched to the jacket.
This is in part an aesthetics vs. function issue here, I suppose.
