quite a few questions. i'm sure the super7s will be fine. A lot of the "weird" feeling in these skis only manifests itself out of powder, so maybe it doesn't matter.
Between the Rocker 2 and the Gunsmoke, it's a tough choice. In true powder conditions, I have a blast on the R2s. But the Gunsmoke is a MUCH more traditional feeling ski, and I think will provide a more stable, versatile ride in Tahoe, where the conditions are frankly not so hot a lot of the time. I know the guns will be great, but if they don't give me that amazing, transcendent feeling of the R2's, I may just get a pair of them as well. Why the heck not, life is short.
I think I forgot to mention I did try the Automatic. Of all the skis I tried, this one felt the most out its element on packed snow. . Just not made for it, but I would love to get it on an Alaskan face some day maybe.For me it felt long and unwieldy and not user friendly at all. The same bumps and tight spots that the Gunsmoke were butter in were a awkward challenge on the autos. Interesting that you liked it. That said, I had the good fortune to see Sage C-A carve on these on hardpack in Utah this year and it was quite a site. Now that dude has a real "race background," that was obvious, knees were practically hitting the snow.
For the other skis you're interested in, I hear good things about the Q115, didn't get to try it, I'm sure the Lines are fun. I would avoid the Shiro as I've learned I've got to have camber underfoot for the feel I like, that's the main reason I don't like the Cochises (and the two layers of metal).
It's snowing in Tahoe, getting ready for a great long weekend.
