Klymit - Wild Aspen 0™ Degree Sleeping Bag

I just picked up a klymit 0 degree bag from big 5 for $40 with their clearance sale.

Been sleeping every weekend pretty much outside. Spending the majority of my time in the wilderness. I have a klymit 0f bag which has been pretty good so far. But I have seen 5f and 10f options which are much lighter and I assume more comfortable. The thing is they are also wayyyyy more expensive. If I'm buying a pricy bag I want to get one and done. The sizes usually follow as 6ft, 6'6ft, and 7ft. While I don't mind a little headspace the klymits large room makes me feel like a cold air pocket is forming around my feet. Which size is best?

I also came from a Klymit bag, which I bought large because I was heavy back when I bought it, which worked good, but wanted a true down (albeit duck down) sleeping bag and not have to take out a 2nd mortgage and that fit me better since I lost 40 lbs. I'm 5'9" and 160 lbs and this bag fit me great. I felt like I was wearing the bag vs sleeping in it and the bag turned with me when I roll over vs me turning inside of it: [https://youtu.be/foIvVFA12xg?si=7GQFK6\_\_tFkSl-XR](https://youtu.be/foIvVFA12xg?si=7GQFK6__tFkSl-XR)
