Please help me choose my first shortboard(s)

Hi, I am 17, 5"9 and 60-65kg.
I am looking for a new surfboard that I will be able to surf with in the Devon and Cornwall area.
I started on a surfboard that was a BIC 7"3 Mini mal (http://www.bicsportsurfboards.com/produ ... u,479.html) and felt confident enough on that board and was standing up every time.
Now, I want to move down to a shortboard to be able to be more agile and perform manoeuvres on waves.
I am looking at boards that range from 6"-6"2, is this the right size board that I should be going for?
If not, what do you recommend?
(Background info: I am very fit and also am a very good bodyboarder, and can drop knee bodyboarding occasionally.)
Thank you!
