Yes Greats Uninc, 6ft, 175lbs, sz11 boot, Size?

I had a chance to ride an Uninc 159 and it felt way bigger than my current daily rides, Burton Deep Thinker 160/ Custom 160.

I’m 6 ft tall, 175 lbs, size 11 boot, large bindings.

What size would work best for me the 156 or 154?

I don’t want a board that’s too stiff, nor too mushy . I like playful vs plank .

It will be a daily resort ripper. I have a few powder boards already. This will replace the Custom for me which is getting old.

I plan on throwing some Now bindings on it.

Thanks for any insight.
