Replying to Beginner park ski + sizing help

Looking to get my first pair of park skis this season. I'm looking to get smth cheap as ive heard beginner skis take a beating. Ive found deals on these skis and i wanted to get opinions and advice:
Line TW pro (178)
Volkl revolt 86 (172, 180)
Head Oblivion 84 (176,181)
Fischer Nightstick 90 (177,184)
Faction Studio 1 (178,183)

For reference Im 6'1 and 165 lbs and ski the alps and in australia
Any help/advice with the skis and sizing would be great.
