It's funny you should mention "cerebral" because that's what was missing in my skiing from the days of my youth to now. Back then, sans lessons, I pretty quickly got up and moving, but I muscled all my turns and being athletic, it was not too long before I was skiing black slopes. Not well, but I got down them and managed to have a lot of fun doing so.
So when I started back I realized right away that as I no longer had the physical skills to compensate for my lack of technique something else was needed. That first day wasn't pretty on those 184 Volkls, but I improved, so I did some reading. I found a couple of articles, one here on Epic Ski, about carving the "Perfect Turn" and the way the writers broke down the whole process of turning, the desire to turn and motion-by-motion, ski-tip, edge and body following, it made a lot of sense to me. It's what I was looking for so I spent a couple of days at Cataloochee and Sugar practicing, then stopping and watching good skiers and what they did that worked. By the end of two days I felt like I was really and probably for the first time letting my skis carve a normal turn. Not all the time and certainly not all that well or stylishly, but better, and it _felt_ better.
In Colorado I tried renting a wider, shorter ski at Taos and that was a big improvement and then the wider Little Big Fats at Wolf Creek. I had to adapt to boot-deep powder conditions and some crud around the edges but I had a great week.
So this time I wanted to get closer to the "right" ski, then, as you suggest, find a good instructor somewhere in NC and get some lessons before this next trip out West.
I think Ghost was right that equipment was a big part of the problem, but if I can get appropriate gear, then I think your suggestion for some long-overdue training is going to get me to where I want to eventually be on the slopes.
Thanks to both of you for taking the time to respond. I'd love to hear other opinions on the subject if there are any that differ with Ghost or davluri.
And is my original premise correct that my weight (a fit 235 lb.) makes those Mythic Riders respond more as a softer ski would and therefore makes them an appropriate choice for an improving intermediate skier? BTW, I found some 178 demo Mythic Riders that I hope will fill the bill nicely.
