If you are down that way, PM a member called SillyShilly or Bulldog, both of whom would do the job for you and maybe at a better price and you can ask them for their view at the same time.
So long as the handle is of the same quality, the only difference will be than the bat picks up a bit lighter - which may have an impact on the balance. If you have a good one, I would say make the investment in the bat you have.
Edit:
What am I saying.
Your son needs a new bat and a new net bat to protect his new bat, and maybe a heavier bat to help him get used to his new bat and his net bat.
