There really is no one onswer to this question.
Every situation is different and will provide you with different means of getting out.
The overall planning of the trade is the important part, not necessarily the routing. Besides, if you are going to trade large positions, there will seldom be any size to get out of on the ECN's(depends on the stock of course) especially if a stock is collapsing, and NX'ing is only good for the first thousand. Also, usually, the specialist will only show a 1 on the bid which will prevent anyone from NXing.
It comes down to: do you think the stock is going lower, if so sell it market. Do you think the stock is near a bottom, maybe wait. But that is were it gets tricky and dangerous because rarely does anyone ever know where the true bottom is.
