One with a fair amount of adjustability. Both draw length and draw weight.

That wayyou know you cancount on keeping the bow for a number of years if you don't have the funds later to buy a new one when you continue to grow.

Think proactive, not reactive!

Other than that, the others have good suggestions and you should definately try shooting a wide range of bows before you buy.

Hope this helps, good luck and have fun in selecting your new bow!
