Help a sister out! Another board size question
Sorry to those who hate these types of threads, but I'd really love some awesome advice from you guys (so much so I stopped lurking and specifically created an account to do it!).
I'm an Aussie girl, 5'7, 145lbs and women's shoe 9. I have recently bought a GNU Ladies Choice 151.5 for a sick price (last years model), just waiting for it to come in just in time for the down under snow season.
Here's the thing – I'm now getting a little freaked out though... have I gone too big? Should have I gotten the 148.5?
I'm intermediate (but progressing fast, surfing and skating since I was 6 might have something to do with it). This will be my first set-up (sick of renting, also hoping to do a couple of trips to Japan and NZ over the next couple of years so want my own gear). I bought the board as an all-mountain (will be my only board), but my goal is to get good in the park, start hitting some jumps/rails etc.
Will I be ok with the 151.5 or should I have gone smaller?
