I am going to Cabela's tomorrow and may purchase a youth recurve for my 9 yr old son. He is going as well. Cabelas sell the PSE youth recurve for $79. Not bad...any other suggestion. My son may not get into or he may go crazy. I have not problem getting him something different in a couple years if he decides to stick with it....look for some insight. I am a novice shooter myself.
Golden Eagle used to sell a youth model called the Brave. My soon to be 6 yr old son was given one. The draw length is long for him and the weight a little tough at the lowest but he shoots it well. I think he shoots his longbow better but the compound is new to him so it gets the nod for now. I think it would work well for a 9 yr old. IIRC they aren't really expensive and would be a good learning tool. There is always a market for used youth bows. If he takes to it, then in a year or two go to a better set-up that can be used to hunt with. Just my opinion.
