This information has made me think about trying a compound again. Shoulder surgery took me into the xbow world, but I may find a 50lb, 80% letoff bow that would be easy on the shoulder and be just fine. Amazing to see data like this and how much BS advertising there is out there. Archery companies are the world's worst at pushing the latest and fastest to hunters. Competition archers need it, but most of us don't. Also, if you truly look at the "progress" of bows in the past 20 years, they really are not statistically any faster, more accurate, or truly better now than they were back then. Now I need more videos to show me what an ethical range is for my Cold Steel spear - she make make a few trips with me this fall!
