Hard to fathom. If so, why?
My guess is that it depends on where in the chain of cause and effect you are in your thoughts. Newton's third law states that there is a reaction force for every force (acting on a different object).
1. You pressure the edge to make it bite, give it grip, stop it from slipping, bend the tips a little more or what have you. You are at the short end of the lever for this with longer skis. This would be a subtle control move that directs the ski, leading to the ski interacting with the snow in a way that provides the major control move.
2. The ski bites, digs in, and the snow applies force to the ski. You feel the reaction force as pressure builds on your shins or wherever. The long ski is at the long end of the lever and more easily builds force. You sense this as (for example shin) pressure and thus find it easier to have the ski build tip pressure with the longer skis.
My guess is you are thinking of #2 above, and you have the lever principal right way round, but a litter later in the process.
As to your theory on level of skier:
I think people who are learning to ski by first pivoting their skis will definitely find shorter skis easier to ski. The skis won't fight back as much, and can be easily muscled around.
I also think people who tip to turn will find longer skis a little harder to control as the force from the tips will have that longer lever arm and a little redirection at the tip will have a greater affect. Mistakes are magnified. It is also harder to put the dipstick in the hole when it's a longer dipstick.
As the skier becomes more adept, the first issue with pivoting
is a non-issue, and the extra control required for longer skis is easily dealt with. At this stage, long skis will only be appreciably more difficult when skiing sideways in rough terrain (Like say they took their SGs out on a hill with a few bumps, but can't see through the ice on their goggles
), not when carving arc to arc turns.
For an advanced skier, there will be more of a challenge with the short skis when going a mile a minute over 6 to 8-inch bumps that would be smoothed out by the longer boards. If they ski fast through the chop, they likely will find the extra length easier to ski.
For an advanced skier with good skills, it becomes a matter of preference and feel. An LR ski feels better carving long turns that a SR radius ski skidding them. Likewise a SR ski is the choice for making those turns.
