As for the other ones I would just try to get a few different sizes.Depending on what the draw weight law is in your state for hunting I would getone at the minimum so the women and smaller teens can use it for your 3-D's but could hunt if so choose to. Along with a 60lbs for the adults. I don't think that you need to invest any money in anything heavier since they are just guests. If they come visit and enjoy the sport(which they certainly will) they can get a bow for themselves.
