SD Ultra vs Aerolite

[Dkuczek]

I have a moose hunt planned next fall and it will be mostly a lake/river in boat/float style hunt. I've narrowed down my gear to almost nothing but bare needs so i can cut on weight/pack. We will be in a cabin with stove but i need to keep weight down as we are being flown in

Items i'm bringing are

Core LW LS
Ambient Hoody
Puffy
Stormfront Jacket
Core LW bottom
Core HW bottom
SD Ultra Pant
Patagonia Waders
Houdini Wind Shirt
Attack Pant

I'm really stuck on what puffy to throw in the pack. Im between Sitka Aerolite, SD Ultra, or Grumman. I have yet to fully get my SD Ultra out in the field for use but last year with my Aerolite Jacket i was the least impressed with the warmth. Weather will be anywhere from 20F to 65F.

Any input would be great!
