Another ski length thread

Hey guys I know you all are sick and tired of these threads but ski lengths all vary on the rider so give me a shot.

I'm 176 cm tall, and 185 lbs, currently riding on a pair of fully cambered super stiff ninthwards that are 176 as well.

I just started skiing park last year, but skiing since I was 7. I have 3s and can slide most hand rails. I spend about 80% of my day in the park. I do about 60/40 jumps/rails. I'm looking at the atomic infamous because I like the r/c/r profile, as well as the slightly wider base and after reading some reviews they seem to be what I want - enough flex in the tips and rails for some butters but stuff underfoot for hitting larger jumps.

Now with that being said, would a 176 be too small? I'm exactly that height but I have a thicker build, also won't the rocker in the tip make the ski feel shorter? On my ninthwards they fit me pretty well however I know that as I progress I am going to outgrow the skiis.
