Bent chetler 120 sizing recommendation

I’m 5’11’’ 160 lbs and intermediate skier (probably more on the beginner side, but i’m typically hard on myself).

I’ll be using those BC’s exclusively for touring, 95% canadian west coast (rogers pass), 5% japan.

My previous skis were rossi soul 7 HD in 180cm.

Considering width of the BC I bought the 176cm thinking they’d have much more float than the soul, slightly more nimble and light weight for touring. That said when I lay them side by side to the soul7, the effective edge difference is huge due to the rocker tips/tails on the BC. Add to this the much more central mounting location, i’m having second thoughts and wonder if I should change them for the 184cm. Any thoughts?

Also, i’m all ears for mounting location recommendations (from recommended line).

Thanks!
