I usually just go through the variations as the song progresses, often returning the more subtle variation A toward the end. I sometimes play my own intros and endings as well, it all depends on the song.

Using 8 registrations per song (one bank) allows the player to quickly scroll through all the songs, title by title in Alphabetical order. I song per registration, saved in a bank of 8 songs, and using a particular genre per bank allows the player to select from the genre, however the disadvantage is that the player must remember which song is located in each bank, which can be somewhat confusing. Lets say you were looking for a country song, and you had 8 Country banks, each containing 8 songs. Where would you look for Blue Eyes Crying In The Rain, which bank would hold it? Gotta have a great memory for that method.

As for the right hand instrument, well that's an individual preference. Some songs sound better with a piano, some demand a soft sax, while another would require a growl sax or maybe a trombone. Most of the time, the OTS settings provide me with the best instrument for a particular song, but not always. That's when I go to my custom voices which are saved in the User Voice section. One push of a button and I have 10 new, custom voices at my fingertips.

It all depends upon what you want to achieve with each song, and what your audiences respond best to,
