Any of the Bowtech "I" cam bows (IE Patriot) will "grow" with you as they use modules for draw length adjustment. As do a lot of bow manufacturers. Brownings cam system has ~4" of adjustment built right in.

The Patriot is a sweet bow, but it also a "top of the line" bow which goes for "top of the line " money. There are plenty of bows out there, just as leathal, that can be had for a lot less. Even in the bowtech line-up the Tomcat and Blackhawk offer great value and performance.

You can skimp on a lot of things, but don't hold tight when it comes to arrows. You get what you pay for there. Beman ICS and Goldtip XT's are a good mid priced range place to start.

Sidewinder? I've "heard" the wrapped fiber optic wires inside the canister "can" cause a vibrating noise during the shot.
