Replying to Volkl Kink

Hi NS
I am currently looking into buying the Volkl kink ski, I live and ski in Australia I am 154lbs and 6'1". I enjoy skiing both on the piste and in the park I am an intermediate to advanced skier on the piste but a begginer to intermediate in the park. I have demoed a number of skis including the Salamon Threat, The volkl wall and the armada el ray. I liked the flex of the Wall but would like a directional ski. Any tips on what lengths you think would suite me and what mounting points were successful for you. Also if you think I am looking in the wrong direction concerning skis any advice down that alley would be useful.
