What bindings?? (Armada ARV 96)

I am getting Amarda ARV 96 skis, either 170cm or 177cm (still not sure, lmk please im 5'10, 145lbs, intermediate skier), anyway I need to get bindings for the skis and I wanted Look Pivots but they dont have any in stock from a Canadian website (no tariffs), so I was thinking of just ordering bindings off the Armada website when I get my skis. I am not the most wise when it comes to ski gear but I am not sure what DIN to get, 12, 14, etc.

So far, I have looked at the Strive 12 GW, N Strive 12 GW, Strive 14 GW, N Strive 12 GW, and to be honest I have no idea what the differences are. I would like some help finding which is best for me and if you have any other recommendations from preferably Armada or any Canadian/No tariff ski website.

Thanks in advance, and if you have any questions let me know :)
