And pressuring the tips when they're the first thing into the turn means you bend them for maximum effective carving with a self-reinforcing feedback loop early (more bend equals more deflection of momentum; more deflection of momentum means more bend...)

ok boys.. try this one on for size. The last thing that you have to think about in a ski turn is edging. You hear it said all the time, "Get more edge". It can't be done! You either have a right angle in the snow or you don't. You can't get more edge but you can get more pressure to the edge that you have. Your standing on an incline surface with a flat board, your going to get the edge whether you want it or not. In every ski turn the ski will go from an edge to flat to another edge. All the ski radius stats can give is an estimate of the skis optimum turning radius. those parameters are set on a very meticulously groomed slope of X degrees, X speed, X weight. the Dynastar test hill in chaomonix is about as pristine a lab hill as can be found anywhere. The ski is tested initially with a robotic contraption that gives all sorts of data.... what you get is a set of stats that will set a general turn radius/range for that ski, length, weight, side cut, base material, bevel, condition of snow at time of test, wind speed, velocity etc etc etc. all considered. Then the ski is given to the on hill testers. The data is always different. With the static tests and the human test, they arrive at what this ski is ideally supposed to do. How do you make a ski turn more? Turn your foot in a smaller circle! I have seen a lot of people get caught in the data trap. All the angulation/inclination calculators cannot calculate the human element. I have never known anyone who could tell me or show me when they are in a 60 degree inclination or put any label of degree in any turn. It's like someone saying, you should be 60/40 in this part of the turn and 50/50 in this part and 80/20 etc. It's great to think it but I have never had anyone who could actually do it.
By staying in the middle of the ski you are using the entire ski. We taught for quite a few years in the early 90's about ball, arch, heel. The modern shaped ski is not a sequentially driven tool. If you load the tip it will always lighten the tail. The biggest problem racers (especially slalom) have today is staying centered on the ski. The boards are so short that if they get back on a turn, there just isn't anything back there to recover on and they had better have some muscle to get corrected or they know they may make the next gate but it will deteriorate from than on. These days
most blowouts on the slalom course are out the back door. The skis are shorter, the speeds are faster, the hills are steeper and the line is tighter. Where once there was a chance to recover, today, it is almost impossible without the conditioning these athletes posses.
Fore and aft loading... Try this experiment,, stand neutral/balanced on a mild hill, skis pointed straight down the fall line. Press/flex your shins "Forward" into your boot tongues. What happens? Nothing, you just keep going straight, but the skis will feel squirrely because you have unweighted the tails. Do the opposite and get back on the tails, same result, nothing happens, you just keep going straight. Now instead of pushing forward on the tongues, push down a little on the balls of your feet and push the boot tops diagonally (towards the front corners of the boots). The skis will come up onto their edges and you will not be able to stop them from turning. The harder you push the diagonal and turn your feet the tighter the radius of the turn.
Most boots manufactured today have a fairly soft forward flex (even race boots) but where they emphasis on strength is placed is in the corners. that is where the drive comes from. If the boot is to stiff forward flexing it will load the tip and slow the front of the ski down and make the tail break loose. (think about a train with about 20 cars on it going 60 mph down the track and the engine hits a brick wall. The engine is stopped but the caboose is still traveling at 60, the energy has to go somewhere.)
Diagonal drive gets the edges engaged, the ski off the base and slicing through the snow.. Trying to work fore and aft on a modern ski will result in a lot of inconsistency and a lot of emphasis on recovery movements. Diagonal drive from the corners will keep the ski slicing.
