For a beginning archer/bowhunter I would strongly suggest you go to an archery pro shop. One with an indoor range that will allow you to shoot several different bows.
And another thing, don't get caught up in the speed craze. When you select a bow pick one that feels good to you and you're comfortable with. For a new shooter, 50# is a lot of draw weight. You use muscles you've likely haven't used before. You might want to consider a bow in the 35-50 adjustment range. Here too a good pro shop will help you develop good form and not start off setting in bad habits.
