Replying to Armada thall ski advice

Hey guys, so I've almost decided on a new pair of thalls to ski on for next year, but at a local retailer they only have them in 181s, I'm 14 5'11" 160 pounds I'm very athletic I'm at the gym everyday, and I ski all mountain and park 50-50 in northeast. I ski hard and fast and I'm just wondering I'm moving on from 171 el reys which were nice transition skis but they broke constantly and were really stiff (2012s). Is 181 too long? And do you think my rossi axium 120s will work on them? Really any advice you have would be great thanks
