New Sleeping bag advice

[C Bow]

I am going to buy a new sleeping bag I have a Western Mounteering Badger 15 degree bag it weighs 38 oz. I have been very happy with it zero complaints. At 70 years of age I am thinking about trying a Feathered Friends Raven UL 10 degree at 33.5 oz or the Swift UL 20 at 29 oz. I will be hunting the Bearthtooths in September. I have been cutting weight as much as possible on everything Thanks for any input

Check out a quilt. As long as you have a good pad. I use a 22 degree quilt with a x-therm pad down into high teens. Super light and very warm.

I've got a Stone Glacier Chillikote 0 degree bag which is amazing.
Anything above 10 degrees or so I use a quilt that is a custom job rated to 12 degrees.
Both are at or under 2#.
