Surfing Waves

Hi
my names wisha and i'm a 14 yr old grom looking for a manoverable board. i was on a 7'6" but i want to move down to a shorter board, i have surfed on a 6'4" and that didn't go to badly. but i think i should go a bit bigger maybe a 6'8". would a 6'8" be able to do cut backs and everything?
Thanks
from wisha

cut backs are going to be a little harder on a longer board like a 6'8. if you surfed a 6'4 with not to many problems, than I would go with a 6'6. That way you wont grow out of it too quick. Once you get good at manuevering on that, than you should work your way down to an even smaller board.
