I don't have first hand experience with the Genesis bows. My biggest advice is to take your son to an archery pro shop and have them accurately measure his draw length and determine a reasonable draw weight for him to comfortably pull before you begin looking at bows. You will want to find a bow for which his current draw length and weight are in the middle to lower end of the adjustability of the bow. My two sons are small and not super strong, so that limited my selection a good deal to find a bow that had a small enough draw length and draw weight. You have to be careful reading the specs on the bows, too. They list a draw length range and a draw weight range, but those are not always independent of each other. The lower draw weights are often not obtainable unless you also use the lower draw lengths, so fitting a child that is tall and lanky and not very strong will be extra tough. I got the Diamond Archery Youth Atomic bow because of those limiting factors. I have been very happy with the Youth Atomic. The draw length can be adjusted without a bow press, so I can do it at home rather than go to a pro shop -- but going to a pro shop is not a deal breaker. I believe all of the major brand youth bows would be fine as long as the bow fits him properly. A lot of parents go wrong by getting a bow that their child can "grow into" and they lose interest because the bow doesn't fit them properly right now when they want to shoot. Some bows advertise that your child will never outgrow the bow because of how adjustable it is. That is not something I would worry about too much unless you are on an extremely tight budget. If your son has a bow that fits him now and he enjoys shooting it and continues to be an enthusiast, you are going to want to get him a new bow down the road anyway even if his current bow technically still can be adjusted to fit him. The most important thing is to make sure he is set up correctly right now. That's my two cents. Sorry I don't have more direct experience with other brands.
