In CAS, do you randomize to get the look you want?

Rarely, especially when I'm redoing an EA premade that ships with a world. But, when I'm doing my own Sims, I'll typically start with a Gallery SIm that has a similar facial structure/shape, as that's one of the hardest things for me to get right, and then change the facial features to match whoever I used as the basis.

Back when I didn't know one could set MCCC to make townies be drawn from my tray--I did it constantly.
