Fischer Motive 80 skis help!

Hi guys,
I'm new around here, and hoping you can help me - i'm looking to purchase the same skis I hired last year, as I loved them (Fischer Motive 80 skis).
Only thing is that I don't know what size to get (168cm or 175cm). I have attached the only picture I have of them. Does that help? The pictures i've seen online have a Yellow triangle in front of the binding, however the ones I used had a blue triangle. Not sure if that's dependent on the size.

Can anyone help me find these skis?

The best thing you can do is hire a new pair and try the different lengths. They will deduct the hire cost from the purchase price when you buy. Also don't be afraid to try different makes and models before finally deciding as it will end up costing you nothing extra in the end.

At least you will end up with the right ski in the right length for you.
