Not sure this will help any, but I THOUGHT the 70# AM35 felt more like a 60# Trykon, and it seriously made my Trykon feel like an OLD Antiquated hunk of junk, from the Draw to the Wall, to the smoothness of let-down, and the feel on release, adding that it's nearly a pound lighter, it's a seriously NICE bow. I too am interested in what an 80#-er would feel like, since the 70 was so smooth and "easy" to pull.
