Will he benefit? Most likely not. What I mean is this. Speed will increase, KE will increase, momentum will increase and bad shoulders will also increase. You reach a point of diminishing returns here. If you're shooting 70# and producing let's say 73 pounds of KE......yer gonna blow through most anything you shoot. How much more could you possibly benefit from shooting 80#?
There's some financial reasons as well. When you go to trade that 70 #'er in, you'll have a much easier time finding someone to buy it. Only very few people shoot 80's making them an item not in much demand.
What he said. I shoot a 70# Trykon and I just can't see any reason I would need any more speed. Consider too that most treestand shots are 10-20 yds. To me archery is a close up in your face sport. I don't want to get good at shooting at 100 yds with a bow. I also don't see myself elephant hunting.
