AR6 Size 181 or 176

Sounds like a good ski choice for what you will be using it for

At your height/weight you could get away with both sizes, but the 181 may be better if you are mounting centre

that is what i was think, also would fks bindings or p series be the best bindings for them

either size would work, i would deff go with the fks bindings way lighter and better all around.

Perfect for what your looking for. I got some 181cm WRS FS /w fks120 and it's perfect. This is somewhat the same setup, both are bomb on groomers, and I would definitely go 181cm if your going anywhere near center. I'm 5'10 150-155, mounted at true center and it's perfect

FKS are a better binding - stronger, but a narrower screw pattern than the P/PX series, so are more prone to being pulled out

In saying that, with your height/weight you probably dont NEED FKS155 or 185's, the 120 would be sufficient but then again not as durable as its bigger brothers..

Comparing the fixed heel PX bindings to turntable FKS bindings, FKS is a clearly better option.
85mm waist on the AR6, so you would need to bend the brakes a little, PX brakes are easier to bend, come with a wider stock width and are more readily available for replacement..Can get wide brakes too.
FKS brakes are harder to work on, come narrower as stock and are fucking hard to find if you snap a pair

If you are all good to bend the FKS brakes, and if price isn't a factor then i'd go for those
