Zak, you may be young and haven't found this out yet, but this is America where everybody (almost) thinks bigger, stronger, and heavier is better. Then you get to be an oldster and figure out that you've abused your body all the past years and a lot of the aches and pains are ways for it to pay you back.

Just for comparison, you do not necessarily get a faster arrow by shooting more weight. More weight demands a heavier, stiffer arrow. I am shooting a 55lb bow this year. My draw is 27.5". My hunting setup is shooting 280+fps. In the past I have shot 500gr arrows doing 180-190fps. Doesn't make any difference. A double-lung shot means a dead deer. I have never had an arrow that didn't pass completely through unless it hit heavy bone. The most weight I have ever shot was 63lbs. But I can shoot them very accurately with no strain when drawing. I hope this sheds a little light on things for ya.
