Which style?

We got our Malibu last year and my daughter and I have fallen in love with surfing! We spent the summer learning to surf on our Hyperlite Broadcast. Both of us have gotten good enough that all the basics are really pretty easy, no problem free riding etc. Now we think we are ready to start learning tricks and we also think we are ready for a new board. Like everyone else we get are knowledge right here on WW and what we are reading is we need to pick a surf style board or a skim style depending on how we like to ride. The issue is we don't know yet how we like to ride. How/when did you guys develop a "style"?
