the inttial presets (and there are quite a few) are a good place to start. When you have some time, start with a mix you're very familiar with. Strip off whatever "mastering" you did and start applying the various presets. When you find the ones you like 'more' then experiment withing themas the settings- get a tweak you like, save the preset by whatever name you'd like so you can up later.
i have saved presets for various arrangements of instruments and vocals (male, female, male harmonies, male vox, female harmonys... etc)
