Man I can't even fathom shooting a long bow with that much weight. I know I could back in my prime but not today nor would I want to. You can do what you please but saying because you can does not make it worth it. IMO if you can shoot that much weight with accuracy think about how much better you could shoot with a bow with less poundage - like your 70# or even a 50#. With a 100# draw long bow and heavy arrows you could kill anything that walks. Good luck to you.
