Replying to K2 Recoils vs Ar7's + ski size

So I have 2 questions. At the end of last year, I bought a pair of ar7's in 176 for a 60% park 40% all mountain ski. Since the end of last year however, I have grown a ton and I am currently about 6' 150. I could possibly return the ar7's and buy a pair of recoils in 179, which people say are closer to 183. Do you think this would be worth it? I'd like to get at least 2 years or so out of these skis, and I feel like 176 might already be a little on the short side.

Also, how do the recoils compare to the ar7s? They seem like they might be better all mountain, but would they be significantly worse than the ar7's in the park?

Thanks and +k to those who help
