You can find examples of it being done big or small. I didn't say that an enrosque is NEVER too big, but that a simple pivot on one foot doesn't HAVE to be. I've been hit in crowded floors by people just extending their leg for a simple step. Just about anything can be led too big for a crowded floor, or at an inappropriate moment. That doesn't mean that no one should ever do the move in question just because some people can't do it safely, smoothly or with consideration for others. Maybe.. or maybe not.. there are so many variables. I'd be hard-pressed to pull Dchester off balance, although I'm sure I could if I tried hard enough. I would think a leader with enough skill to pivot cleanly on one foot would also have enough experience to have determined already in the tanda just how stable and consistent the follower is in her own execution of a molinete. You may also find that others don't agree that having both feet down allows for quicker changes and compensating to avoid crashes. One could also make a case for the idea that having one foot already lifted means you are that much closer to placing it wherever you want. That is usually the case for followers, and one of the whole points of coming through the "collected" or neutral position. I think this is going to have to be one of those "agree to disagree" things. Several other leaders have chimed in that they can do the pivot in a tight space and/or are just as stable doing it as when they have both feet down. These things may not be true for you personally, but that doesn't preclude them from ever being true.
