I just spent the past two days skiing these two skis at Stratton Mountain in Vermont. Conditions today were packed powder groomers (really…very minimal ice/skied off patches!) and no crowds at all, so the conditions held all day. Yesterday there was a bit of fresh snow on top of the same…more people on the mountain, but light by Stratton standards.
I'm an advanced but not expert skier, 46 years old, 5"11, about 215-220. I ski all over the mountain. Stratton's terrain is very fun for cruisers but nothing extreme (I don't ski the woods). Both skis were 176cm. A lot of people on the lifts were asking questions about these skis, so I'd thought I'd review them here. I know there is a lot about these skis on this site-that's why I own them!
These skis have similar tip and tail dimensions-122/78/105 and 122/84/110. Both have metal layers-thinner on the FX84. The FX has a tapered tip (no rocker on my version) and a flat, rounded tail. The MX78 (no plate on mine) has a squared off tail, upturned just a touch. If you are thinking of buying one of them because the dimensions look good for the East, know that they ski very differently. Both are really fun skis and I had two of my better days of the season on them.
The MX78 eats up a lot of terrain fast. I felt very confident at speed on them. Edge grip was great. This ski made me stay focused on technique because it was just such a fast ride. On an empty mountain today I felt like it was the perfect ride for medium and big turns. For me this wasn't a "playing along the edges" type of ski. When I tried to make tight turns in steep terrain I had to incorporate a bit of hopping (which was fun also). I liked the locked in feeling the ski gave and the powerful way the ski finishes turns. For my level of skiing, this ski is the ideal groomer ski. If you are looking for a groomer ski for the east, this ski deserves a demo. I didn't take them into the bumps. (BTW, purchased these from Dawgcatching in December at a great price!)
The FX84 is a ski I've had for a couple of seasons. They may be a bit short, but I bought them essentially as a bump ski and a mellow ski to use on the smaller local mountains I sometimes ski at. As has been mentioned by other reviews, this ski has a lot of power in a light package. I could use it as a groomer ski and have fun, but one thing to keep in mind is the tail…it's shape does not give the same feeling as a true groomer skis. When going really fast on these skis I had to be careful how I finished the turns on groomers or areas without loose snow to turn on. This might not be an issue with lighter skiers or in a longer length ski. The rounded tail did make it really easy in moguls and broken snow. I had a blast with this ski in moguls and in the few natural snow trails at Stratton. This ski is so light and flickable. This is a great "playing along the edges" type of ski. I had ton of fun on it…for me it is the most playful ski I've ever owned. Its horsepower is an added bonus. Very versatile!
