Mashing the tounge is not in vouge, but modern race technique involves putting the skis on edge very early in the turn , and letting the skis bend the boots. If you are skiing in boots too soft for the skis you are on, you most certainly will not be able to get the full performance out of that ski.
Here's HH skiing those big big 150 flex plugs a few months out of knee surgery, how does such a little guy like him do it??https://m.youtube.com/watch?v=o6DLRCZLbmU
Ah, that explains it! Now i realize you are a closet adherent to that system that shall not be named but sounds like a monthly problem.... And yes, i actually watched the video, never having paid attention to HH before. Explains a lot!. Nice skiing, i am old enough to remember when having your legs locked together like that was a sign of a good skier! . Too bad equipment and technique have moved on!. But of course if it is good enough for he who is not supposed to be named, then all his disciples must duplicate his equipment exactly, regardless of individual physique or ability
It does explain a lot though. If you want to ski with your legs locked together then use a super stiff boot and a noodle ski so it looks like you are bending it.
OTOH, if you want to adopt more modern dynamic technique that takes advantage of equipment advances, get your feet apart, drive leg extension and use the fore/aft movement afforded by a boot that is laterally stiff but allows the necessary fore/aft flexion that enables you to get a wide platform that drives the ski. If you ever get out of your Helly Hansen adherence, take a look at Ligety sometime. If not, I can send you some fluorescent gear that will properly match the period skiing..
