"Love to get a pair of the Cho Oyu out (skiing) with a set of Dynafit Race bindings
screwed on them."
"Both the Cho Oyu and the Nanga Parbat are offering some pretty wild, modern and
lwt technology for "speed touring" skis. I have no doubt from my limited use of
the Cho Oyu that either the Cho Oyu or Nanga Parbat are going to be great ski
mountaineering ski. Sad it will take another winter season and some deep snow
to comment any further. But for some winter conditions the Cho Oyu especially
might really offer some unique soft snow surprises. All in a very good way I
suspect. Good turns are only 4 months away if we are lucky.
Really makes me think about having a short Nanga Parbat for the weight reduction
and Spring conditions. And a longer, wider Cho Oyu to ski on winter snow."
I ended up going with my gut on these and bought a 174 Nanga Parbat and the 182 Cho Oyu and then added Dynafit Low tech racing bindings to both. I also added the heel adjustment plate to the Cho for my other boot options (+30g). Dynafit plate gives me a 32mm leeway. 16mm from center either way. Which is huge. I don't like "rental" bindings.
But in this case the plates offer a a lot of sizing options for the additional 4mm of heel ramp and 30g. The Nanga is set up specifically for my PDG boot BSL. But the Cho offers too many advantages as a all around ski to ignore, so it has to have the option to use all my boot variations. All in, the cost was a significant investment for me. My plan is to use both hard for more than a season or two!
Here are some numbers for comparison:
all are one ski weights with a Dynafit Low Tech Race, with steel springs (not Ti, +10g) mounted
167 x 74mm Broad Peak 1320g
171 x 80mm Nanga Parbat 1170g 174 x 89mm Cho Oyu 1210g (three pairs of 174cm have weighted in @ ant where from 1100g to 1180g per skis)
182 x 89mm Cho Oyu 1340g
182 x 106mm Grand Teton 1800g
177 x 112mm Huascaran with a Speed Race binding @ +70g for the binding is 1980g or 1910g as a comparison with a Low Tech.
Last season my 177cm Huascaran convinced me I could use and really enjoy more ski in any conditions, year around. But I sure didn't want to carry more ski for weight than my Broad Peak! The Nanga Parbat is a longer/wider ski than, and beat the weight by 200g of my 167cm Broad Peak. And the Broad Peak is one of my all time favorite skis for any terrain. The 182cm Cho is longer yet and 15mm wider while only adding 20g. (50g total with the added adjustment plates) I am not worried about the added length on either ski. The modern rocker profile on both lets them ski much shorter than the measured length. The 174 Cho skied hard spring snow like a shorter BP for me. It actually felt like a shorter 167 BP! Which is saying a lot I think. So I am expecting really great things from this 2 ski quiver.
More to come as the season progresses on my impressions of the Nanga and the Cho. The Dynafit TLT5 boots changed how we think about touring boot weights and performance. I think the newest Dynafit ski technology will eventually change how we look at touring skis in a similar manner. I am now holding out for a short (177cm) 110mm+ under foot ski @ -1400g. Trust me, it is coming! Keeping track of the lwt ski mountaineering technology just the last 3 or 4 year will tell you that.
I have come to trust Dynafit skis more than any other brand to date for my own use. In just the short time since the Spring of 2011 I have gone back to Dynafit over and over again for my ski needs. First the Seven Summit, early on. Then the Broad Peak became my light weight stand by. Last ski up from the Winter through to Fall of 2013, the Huascaran. I ski on other skis brands which have different uses for me. All of them, by choice, exceptional ski. But I have found the Dynafit brand seems to keep coming up with skis that really fit my desired use. Hard to ignore these two new light weights if you worry about the up and the down like I do.
