Bud, I totally agree.
Next Saturday I'm playing a three hour dance and will probably go through about 50 or more songs. I don't like to use the same style more than twice in three hours, and then carefully separated by about an hour or so. I may use the same basic style more than that, but altered with different intros, endings (or no prerecorded intro at all), and some parts muted.
This has nothing to do with how good or bad the built in styles are, only the need for variety.
So-o-o-o-o, I still continually look for new styles and steal the good parts and put them together as a custom style, almost always taylored for a particular song, and only used with that song if possible. It takes time, but worth it. Also, as time permits,I continually try to upgrade my styles because some that I have done really do need refining.
