4 Frnt Hoji

I just copped a pair of Hoji's during a black Friday sale but a little skeptical about the length. They only had 177cm left in stock hence the low price. I bought them because why not and I can return them as I haven't mounted them yet. I'm stuck thinking should I just shell out an extra $250 for the 184 and return this or not.

I'm 175cm tall, living in Norway, ski pretty aggressively mostly freeriding, do FWQ comps etc. and split my time 50/50 resort and backcountry. I'm planning to use these as a soft snow specific ski for both touring and resort and plan to put a shift on them. I'm going to Japan for 2 weeks in Feb and was also planning to use them as my main ski there too.

My thinking was the shorter size would be lighter to tour with and more nimble in the trees but obviously they will be less stable at speed but now I'm wondering if they're actually just too short full stop. What do you guys think?

Rest of my quiver is Fischer Ranger 102 FR 177cm as my daily driver, Volkl Revolt 95 park ski and 2015ish BentChetler 184cm (also bringing to Japan but will be sharing with a buddy)
