I'm 53 and have been shooting traditional since I was 5 years old. First bow was a 15# hickory flatbow, shot it for 2 years. Then Dad bought me a 45# Bear Kodiak,(still have it, believe it is a 1955.) Yes, this is heavy for a 7 year old; But Dad said,"Shoot it, Your not getting another one till you can shoot this one." (Found out years later he got it for free and couldn't afford to buy another one.)
Well I did learn to shoot it, and buy the time I was eighteen I was hunting with bows from 50 to 90#s. I most commonly used 75-80#s.
After 48 years of bowhunting I still hunt mostly with 65-75# bows. They just feel right.
Never have and never will own a cable gun. I was shooting Trad when everyone was aiming cable guns. That's how I got the name Bawana Bowman. Been called that since about 1975. I believe the movement to lighter weights is related to the fact that so many shooters are returning from or have always shot wheels. The majority of them don't have the ability to shoot a heavy weight trad bow. Thought they were really something when they drew that 70 or 80# wheelie, then found out how it feels to hold a real bow at full draw!
Got to admit one thing though: If it were possible to snap shoot a wheelie I may have moved that way when they first came on the market. Glad I had better judgement, even back when I was young and knew everything!
