OK, to start, I already have a plenty fine setup of a synthetic bag & puffy, so let's not get into the down/synthetic debate here. However, I've come to see the light and am looking at getting a down setup for the niche use of 2-4 day fair weather climbs in the Spring-Fall season to keep my pack smaller. I also have some alpine trad climbing plans that require carryovers, so naturally weight is also a consideration here.
1. I'm wondering what some climbers here recommend for a light, small compressed size down setup for say, 0 to 20 degrees, though most especially in the 20 degree range. I tend to stay warm when climbing but get very cold when sleeping, so it is worth losing a bit of the weight/bulk advantage to being comfortably warm in the high 20s at night.
I'm especially looking at Feathered Friends and Western Mountaineering bags, although I don't mind trying to be cheap so long as the bag stays reliably warm, compact & light, though the durability and waterproof features are less important to me.
2. I'm also being tempted with the idea of getting a half bag and supplementing it with a warm down jacket, which can add some versatility to the system, although it might not be as comfy. Anyone have opinions/suggestions about this setup vs. a full length down bag and me optionally bringing my current synthetic puffy?
Specifically the system I'm thinking of here is the Brooke's Range Elephant Foot bag combined with the Brooke's Range Alpini Mountain Anorak Hoody
