HUmmm, to be honest the 16 scares me , you still have a few years of growing and you are going at a fast rate. If you were not going to grow more I would say yes the board is fine for your (granted I know nothing about this board). But if you feel that might grow more then no. This is the thing as far as height and weight the board can take a few extra pounds and inches, but if your feet grow another inch then you would need to get risers.
I guess it comes down to what you think is right. It's sort of a pain in the ass, because you don't want to get a bigger board either specially for park, what if you don't grow more... then you're fucked.
But yeah like I said for the present stats the board should be fine. You have a little thinking to do.
Are you parents taller than you?
