OK, I just got back from Mammoth where I spent 6 sun filled days of skiing. As most places out west, Dec and Jan were a bit dry. But at the last minute, Mother Nature dumped 4 feet of snow over 3-4 days right before our arrival. That opened up the mountain a bit, and gave us some off trail excursions that we would not have had otherwise. However by the time we got there, the only freshies to be had was unskied frozen crud in the areas that still had plenty of rock showing. So most of the week was skiing fresh groomers in the morning giving way to lots of scrape piles in the afternoon. Off trail conditions ranged from dirt, windpack, packed powder, hardpack, bumps, rocks to the occasional pocket where some soft snow blew in. And I must say that the E98's performed admirably in all of them, including the dirt and rocks from the look of my bases.
On the fresh groomers in the morning, they were outrageous! I was able to lay down some serious RR tracks with ease. Later in the day as the groomers got scraped, the 98's barely noticed. Off trail they handled hard bumps with ease as well as broken crud. Wind pack and hardpack not a problem as long as you set an edge, which is fairly easy to do. I also liked the way they felt in the occasional soft snow which left me longing for a big dump to try some powder out, but not on this trip. At speed, I don't think I have skied a more stable platform. My cousin had the Mammoth app downloaded to his iPhone which tracked where we were and gave, vertical, top speed etc for each run. I borrowed it for a steep groomed run off the top of Chair 3 and apparently hit 61 MPH without really trying hard. When you have this ski on edge, you feel like you are on rails and invincible. Very, very stable. It always amazes me that a ski this big and wide can be so quick edge to edge allowing you to make quick tight turns to avoid rocks and boulders. Yet they weren't a chore when you needed to go slower where approrpriate. By the end of the week, I was really liking this ski and looking forward to trying it in some softer snow and some trees, hopefully in March when I go to Big Sky.
About me, 57 year old mountain master (I prefer that decsription to "expert"), 5' 9" 190 lbs. Rossi E98 180cm mounted with Marker Jester Schizo bindings set 1.5cm (15mm) behind the mfg mark. Lange RX 130 boots, Leki Trigger 1 poles.
Hope this helps someone.
