Replying to Reckoner 102 Feedback and Sizing

I'm likely to pull the trigger on some Reckoner 102s, got a decent deal lined up.

I want a ski that is good primarily for messing about on-piste, carving, learning butters, hitting the park etc. I am a novice freestyle skier.

It doesn't need to charge high speeds/ plow through chop. I have a Sego Big Horn 106 187 for bigger days and it is legit. But, I don't want the Reckoner to be an absolute noodle that is going to feel squirrely at any speed if I do decide to take it on some steeper/ less easy terrain every now and then.

Basically, while the 177cm would be better for park and messing about, I'm wondering if it would let me down for other use cases, even if I dial it back.

At 5"10 185/190lbs should I go with the 184, or 177 given people's experiences?
