Look at last years twin tips at your local shops
scratches, 1080's, Fujatives, or silencers would all be great.
You are about the same weight as me but a little taller so I would suggest going with a ski in the 180ish range, I started on and am still riding 180cm AR5's and love 'em. Good luck getting good at halfpipe in your first year, today was my 11th or so day of skiing and I'm just getting 180's down, still have yet to slide a box well though.
