I just finished skiing 4 days with Harald at my home mountain in Montana. We got 50" of snow over 4 days and yes my legs are shot! The first day we had 16" of fresh overnight. We both decided to go wide and I whipped out my 2 pairs of Rev 105s that I hardly ever ski because we never get dumps this big (until this year where we have had some crazy stretches of fresh snow with 1-2 foot dumps occurring often). Conditions were much more challenging than we expected as it had been warm and we had hard sun baked bumps underneath and often you couldn't really tell what was beneath the pow. The one thing that was very evident on the Revs is that they did not want to come up and out of the pow and it was requiring huge energy to flex massively to get the skis to come up. After 4 runs on our ridge we both grabbed thinner skis. I grabbed my Kastle MX 88s and Harald grabbed my Head Monster 88s and we went back up to the ridge. Wow, a game changer and very enlightening. Harald was telling me to ski a tighter line, kind of like a zipper bump line. The move was to get early high C engagement and then big ski bend into the apex of the turn and done properly, huge rebound which was popping the skis right out of the pow. Now to say that I could not get the Rev 105s to do this probably will surprise no one. But Harald could not no matter how hard he tried. As soon as I started to ski this way I was first blown away that I could do it but then I was blown away with the Kastles. My first day on them had been in similar conditions and clearly what separates theses skis (and the monster 88s, the old RNRs) is that they will bend and they will give great rebound when driven properly. This is the PMTS way of skiing black and double black terrain. And if Harald can't do it on a fat rockered ski, I feel confident saying that on one on this forum can.
Day three brought another 16" after we had had a measly 10" on day two. I decided after our first several runs on the ridge to try my Liberty V92s and see how they performed. Well they engaged the high C nicely. They bent nicely into the apex, but there was no rebound. no pop out of the pow. Harald watched me on two runs and said I was skiing correctly but that the skis just won't perform.
Now not everyone can or wants to ski this way and I found those liberty's to be a very fun and user friendly ski until I started to attempt these types of turns.
I also firmly believe that fat rockered skis have enabled many people to ski terrain and conditions that they would not have been able to without these advancements (and thats a good thing except when they are stealing my pow ). And 5 years ago I couldn't make these turns so a little rocker and a fatter ski in deeper stuff seemed to help. Clearly now it is not and is actually making things harder.
If you have the BPSRT and you can ski it in black and double black terrain and in challenging conditions, thinner with camber is the only way to go. BTW Max says the RNR makes this turn great. I will take mine out and test them next decent sized dump we get. I should also mention that half way through day 3 with the 16" HH switched to my 176 Blossom White Outs and he was even happier than he was skiing the Monster 88s (so clearly this ski works great off piste and in fresh snow with these type of turns.)
