I also think that there is a very wide variety of ways to transition from turn to turn, and the duration, intensity, rate, and timing of the movements can be varied to create a virtually infinite variety of possibilities.
I think about two extremes being inside leg extension (as promulgated here by Rick/Fastman) and the weighted release (keeping the pressure on that old outside ski well into the new turn... perhaps all the way to the apex). Movements to cause these two transitions are also widely varied, but some are more efficient and effective than others. My goal in all my transitions is to maintain ski/snow contact with both skis at all times from the apex of the previous turn through the apex of the current turn. This means no lifted redirection, no unweighting, no blocking, etc.
When I find my turns feeling interrupted, I go back to this goal. I check and see what I'm doing from the apex of one turn (which I view as the beginning of the transition) through the apex of the next (the end of transition). In fact, I guess I'm often thinking of "turns" as really "linked transitions!" Smooth, precise, and powerful.
