When I hear referances to the ski tips drawing or pulling the skier into the falline I invision a skier with release timing that is so too late that their CM must be re-directed down the hill, aka no flow park-n-ride.
I prefer the perspective of the released CM actively flowing to the inside of the new turn such that the skis must arc into the falline just to keep up!
This is what produces the feeling of being upside down that Martin Bell refers to.
I see most skiers hanging on to the re-direction of the CM too long and missing the optimum point to start releasing leg tension so the CM can go more directly where you want to go without taking the out and around, or huck up and over, scenic route.
Skiing clean and dynamic Arc-2-Arc does not require a heavy carve in the top of the turn. Feeling heavy at the top of the turn probably means you released too late and needed strong re-direction of CM back toward the falline. Optimum release timing produces just enough pressure to bend'em just as much as needed, but no more. Excess pressure in the top of the arc usually leads to even more excessive pressure in the rest of the arc as well. Skilled release timing and presure management can make the differance between working really hard at arc'n for a few runs till your legs die, or arc'n just hard enough all day till the lifts close.
Arcimundo is best expressed as carvimotion via perfect pressedgulation. (Inspired by The Fonz)
