RE: I need help buying a bow for my son
What size is your son? That is the main factor. Draw lenght mainly will decide what bows he could shoot. Just take him to a local shop with bows they should be able to set him up. That being said go with a PSE I love them. Thunderhead Broadheads will probably be your best bet 75 grain. Get whatever Carbon arrows you can get for cheap and you should have a good bow.
