60lb to start is alot. Take look at 40 to 45 lb to start.70lb with 65% let off is only 24.5 lb . Learn how to shoot first then work your way up.Take a look at used bows, With a used bow you can start low and when you are ready to move up inweightyou can sell it and get your money back.
I've been shooting since 1972, I sarted with a 45lb pearson then when I was 16or 17 (a young buck)moved up to 90 and 100lb bows now I'm down to 45 to 50lb bows( growing old sucks[:@])
