I just ordered a Hoyt Alpha Max a couple weeks ago and am really pumped to get it. I'm moving up from a Mathews Ignition that has served me well for the past three years. I understand about your draw length though and have the same problem as far as the small and local bow shops just don't stock those lower poundage bows for us girls. I spent an hour going back and forth between the Mathews DXT and the Alpha Max and decided on the AM for the simple fact of the way it felt to me. I LOVE the grip!! Another you may want to consider that I've been hearing a lot about is the Mathews Mennace. I think you can get the draw length down to like 17" and the draw weight goes up to like 52 or 55. Of course the max. weight depends on the draw length. I've heard it's a really good bow for women and youth. In the end, you have to go with what feels right to you. Hope this helps a bit.
The sacrifices that you make when bringing your kids hunting with you, in the end, don't feel like sacrifes at all!
