I recently put a set of Nitrous "C" cams on my daughters Martin Leopard, with mini mods it goes up to about 27" to 27-1/2", so it should go down to about 24" to 24-1/2", and with regular mods it should go about 2" longer than those numbers (so plenty of growing room).
It just depends if you want to take the time to find some cams and mods for it, or if you just want something straight off the shelf.
We bought the Leopard for her in about '09, we even had it custom powder coated for her, and all was good for a little while, until she had a growth spurt, and soon ran out of adjustment on the mini M-Pro cam that comes standard on the Leopard, and goes to about 26" DL.
Of course, she wanted to keep her custom bow, and had been asking me for a while if we could put a shoot through system on it, so I took the Nitrous cams and mods off my SlayR and put them on her Leopard, I'm not sure how fast it is, but it seems pretty quick compared to all the other kids bows that she shoots against (she loves it)
It went from being a 40 pound bow with the mini M-Pro cam, to about 50-55 pound with the Nitrous "C" cams on the same limbs. (I've had to turn it down a fair bit for her to be able to shoot it comfortably all day) so plenty of growing room there as well.
And now she is just about out of adjustment on the mini mods, so I eventually managed to scrape up a set of regular mods for it (still in the post, thanks Don), my daughter only just turned 14 about a week ago and she already has a draw length of around 27"
