I might add that with a softer deck torsionally, edge to edge carving will be really hard to do without engaging into a dynamic crossunder turn. This is because you will tend to favor your nose foot to roll over to the heels with your tail foot trailing it no matter how evenly you try to distribute your body weight. With a very stiff deck, there is not enough torsional flex for this to matter, but for a softer, park/freestyle or beginning deck, it will result in a crossunder turn unless you really exaggerate driving edge to edge by using of the shoulders. Newer mid-width park decks have become torsionally stiffer over the years for better edge to edge response, but I still find myself naturally crossing under if I'm hitting particularly steep grades, especially if the conditions are hardpack. dustpack or crust on my jib deck.
