100% agree with Country. Even though the youth bow will go down to 17" draw or 15lb draw weight it is going to be heavy. My daughter started out in 4H archery last year using a Bear Apprentice III. It is faily light, I think about 2.8/9 lbs. you can find them on eBay still NIB. She will be 11 next month and now shoots a Mathews Ignition. She really likes it though you have to change cams to change draw length. I would say she is about average build/height and shoots a 21" draw length and 24 lb draw weight to get you an idea.
In addition to the Diamond, another to look at would be a Hoyt Ruckus or Ruckus Jr. You could also look at the Genesis or Genesis Mini for a compound/zero left option.
I may have a basic sight, release,or rest laying around. I will check and send you a PM if I find something that she could use.
