As far as "my" preferred" way of opening my hips to the hill are concerned...upon exiting the fall line in a sufficiently angulated/countered position, the skis will begin to move more across the fall line (though not necessarily perpendicular to it...depends on the set) The centrifugal forces that are encountered here are (or can be) great. In order to move through transition and into the next turn, the skis need to be "released" (otherwise they continue arcing for far too long) by lessening angulation, and counter, (and edge angles as a result of this). Foot steering also plays a role in this release as the femurs begin to rotate in their sockets back to "neutral" or "square".
Of course, transition type plays a major role in this--are you going to retract (swallowing or avalement), and leave the CoM relatively down (tho vaulting to some degree still occurs), so that you can get onto your new edges quickly, ala, a more down the fall line set, or are you going to extend the legs, and move foragonaly, to achieve greater distance across the hill with the skis--while leaving the Center of Mass inside? If the former is done correctly " hips open to the new turn" should not be a problem, as the body is usually facing down the fall line (more or less, there's plenty of photos showing otherwise) as the legs extend laterally back and forth under the CoM. If the latter, after squaring slightly during finishiation, the CoM moves down the fall line first as the skis still continue more across, (this is how we "catch back up" and create good turn shape, rather than lingering forever behind) This movement also helps facilitate the rolling of the edges (new outside is still "uphill" while new inside is still "downhill". Assuming the new inside leg begins to "collapse" while the new outside becomes "long", then such positioning requires (or at least, strongly encourages) open hips to the new turn.
