Muzzleloader for a kid???

[spin05]

What be a good muzzleloader for a kid.My boy is small for his age and wont be able to pull the 40# for a bow for a while. Ive been looking at the knight wolverine youth model,the CVA buckhorn,and T/C black diamond. Im looking for the lightest one possible.So far the CvA is the lightest and priced right too.....
