I’m on year 3 with my sawtooth & am very happy with its comfort & carrying ability- 80 lbs is a piece of cake you will really love it after your first pack out.
Take the time to get it adjusted properly try going just a little shorter than you think is right to get it to stay on your hips. I’m using the Kifaru gun eater and the same holds true. Now that it is adjusted properly the hands free & fast deployment of your rifle are great.
The guide light frame makes a perfect field rest too. I love shooting off my pack from a sitting position now. Sight in at longer ranges using just the pack every year out to way past where I’d shoot I’m good of that upright frame.
