An indirect observation: I've been almost exclusively skiing the Ogasaka TC-SU in 170, which has a far more substantial mid body compared to the XCs. Even without the plate the Ogasaka's are a lot stiffer under foot, but with softer tips, whereas the XCs have a smooth, continuous flex throughout the length. Not surprisingly the Ogasaka's hold an edge better -- I've had a few instances of loss of outside ski hold on the XCs in a hard turn, none with the Ogasaka's. Both skis are a lot of fun in bumps when the snow's good. But the Ogasaka's are lighter and with their nonlinear flex, I find they tend to get thrown around in firm bumps with crud. The XCs are heavier and have better suspension and ski better in these rough conditions, at least for me. In the RC thread I mentioned how the XCs bumped up the fun level compared to my wider skis when a powder day turned to Cascade concrete. The same is true for colder, firmer conditions: bumps + semi-frozen crud chunks.There is so little information out there on the XC. I appreciated your previous initial impressions of this ski. Any comments on the XC you would be willing to share since your Jan 2 post? I am nearing a decision on a frontside ski and would greatly appreciate any insights.
Another indirect observation: My son and I were at Whistler the other week skiing on firm ice -- temps were down to 5 f in the morning -- he was on his RCs (165) and I had my TC-SUs (170). We swapped for a run and I immediately noticed the tails on the RCs were "soft" relative to the TC-SUs, so I would conclude if it was down to RC vs XC for that day in Whistler, I'd prefer the XCs.
Yet another indirect observation: I like skiing the Head eRace Pros (180) in bumps and steeps on low snow, soft snow days. The length and the flex work well for me. I suspect the XCs in a 181 would be just as good, maybe better.
