Something the local shop does is take a 40-50 lb draw weight range PSE Nova with a draw length range from 23-27 or 24-28 inches and short string it by an inch or so. This decreases the draw length range slightly and lowers the draw weight thus making it a better fit for a young shooter (though the youngest I have seen this done for was a 10 year old). The cams are still in synch with one another but the timing is off. This does not affect accuracy or shootability in my experience but does allow the bow to cover a drastically larger draw length and draw weigh range. This in turn allows the bow to really grow with the young shooter and it only costs $4 or $5 for the slightly shorter string. As the youth gets older and wants more draw length or draw weight then the original string is again installed and the bow continues to fit the shooter.

Just a thought as alot of these "kids bows" can cost close to $225 and higher yet the PSE Nova normally retails for around $180 locally and yet could last potentially much longer.
