I don't bring an extra as an emergency spare...My philosophy is that it is always a good thing to have more than one tool in your toolbox.
I bring at least two - usually a 5 string with flats and a 5 with round wounds. Sometimes a third - a 4 string with round wounds. And sometimes I bring my upright and an electric. I change during the performance depending on what fits the style of the song.
