Now that I think about it, when I do not use head cement I do a double whip finish. I use Veevus thread and I feel I can crank down a lot harder on the whip finish....something I could not do with my old thread. I still must have some doubts on neglecting the head cement since I feel I need to double up on the whip finish and crank down on the thread. It doesn't take much more time to add the cement but when I crowd the head (a technique I employ way to often) the cement has a tendency to fill the eye of the hook......and that takes time to clear at the bench or on the stream. Thanks for the responses. Its nice to know that at least some times head cement is not needed.
