Sleeping bag for double duty

[Lowg08]

I’m already in the market for a additional set up. I’m thinking of adding a hammock system for earlier October hunts with under blanket and all. I already have a 0 degree bag for my floorless shelter. 0 degree marmot had to up grade to a wide after this year. I’m sure that bag would be fine for both but I’m wondering if there is a better bag that would compliment both styles better? Keeping weight with in mind
