Well I read all of the posts so far and thought I'd weigh in on this seeing as I'm one of the young ones talked about. I'm 28 now, and started shooting a year and a half ago. Didn't switch over from compound or anything, just wanted to shoot and hunt with a trad bow. Also had never been hunting before either, and decided I wanted to do that too. I spent a lot of time outside in the woods as a kid, but never hunted.
Now onto the topic. I'll start by saying that prior to shooting I was in the military for six years and did more than most, when it comes to training and deployments. I picked up archery when I got out of the military. I also picked up body building as I've always been big into working out. For my size and body weight I can move some pretty high numbers. When I first started shooting I bought a 65# recurve because I'm a strong dude and I should have a heavy bow. I could pull the weight fine, and pull it often. I also like to hold at anchor for a second or so to steady my shot, snap shots aren't my thing.
The reason I dropped down to 50# is because I can shoot it all day and not feel fatigued. I'm hunting deer with it, (not successfully) and don't personally feel the need for more. Most of my time shooting is at targets and 3D. Can I shoot heavier bows, of course. Do I enjoy it, not really. I shoot trad for fun, I enjoy it. I don't feel the need to break a sweat sending an arrow down range.
For those of you who feel that the younger generation is weak, or not as "manly" as generations past. That is simply because the best are away fighting the war and you are seeing the ones who stayed behind. Believe me, I had the great privilege of serving with the finest sons our nation has.
