Yeah, well, I have both the Rictor 80's and the Nordica Steadfast so here's my opinion:
I'm 5'9" 140lbs and excellent skier. trust me!
Rictor 80 174cm: My go to all around ski for east coast skiing. Does it all for me except the pow days which are usually few and far between (depending on......). I have pushed the Rictor to it's max speed, it is not a "fast" ski on the snow, but adequate. Bumps very compliant. Fresh man made snow, piles of it, etc. the ski has enough width to "float" over that, not too bad on the golf balls, little bouncing around. For me it's my go to ski, just throw it in the trunk and go and feel confident it'll work anywhere except pow. Trees fine, quick reacting.
Now the Steadfast:
I demoed the Steadfast in a 178 cm which was fine for big open groomed trails, or trails with a little itsy bit of slough on them. This is not a powder ski. It worked best on groomed trails w/maybe an inch of snow, any more snow and it seemed out of it's element.
That being said I bought the 170cm length thinking it would be better and more maneuverable for bumps or trees. NOT! This ski was more forgiving in the longer length. It follows Nordicas flex pattern of having a stiff spot in front of the binding to the tip so it's not forgiving in bumps and you will get "bumped" haha around. Definitely has a solid GS Racing ski feel, would describe it as a wide racing ski, not for pow. It will take you for a ride in bumps and trees, no forgiveness in this ski.
So, for me I'm gonna try to get another pair of the old Rictor 80's or go with the new 82's and a pair of the 90's for those east coast "snow" days. Now which size do I go with the 170 or the 177, darn I wish they kept the 174 length, it was perfect. Life is a give and take.
Hope that helps.
