Replying to Rookie in need of twin tip ski advice

whats up guys, cameron from tn here. i skied a bunch in high school on carving skis and basically had to drop the addiction due to college costs. i got my first real job and the addiction is back. i want some twin tips! here's a few questions.

i'm 6'1" 170 lbs. intermediate skier. My old carver beginners were around 165 cm i think. I've heard twin tips run a little shorter so would 180 be a good fit for me? I can't break the bank either so i've been looking at salomon 1080's from a couple years back. good choice? always if anyone has a some used twin tips i would be interested in that for my first pair. excuse my ignorance, thank you.
