I have gravitated to using a method similar to Don's. This weekend, I used that method to set up two Waltz registrations, one for slow waltzes and one for fast waltzes. With a different style in each registration, that makes 8 available for both slow and fast settings -- that handles all the 2000 has internally plus room for one or two stored in the user area. I put the styles in from lowest suggested tempo to highest; styles on the "fast" version ranged from 150-200 something. I then noted the main voices available in each style and made sure the voice saved in the registration provided a fifth option. I also made sure each of the 8 registration voices were different instruments. Thus, there were always 12 solo instruments available for each style. In the registraton button, I set the left hand to the instrument I preferred, usually a grand piano, but sometimes nylon guitar, or strings. The OTS presets include a left hand voice (although usually it is not "on"). If you want a different left hand, put it in the registration button. Now when you press that button to call up the style, you can freeze the style then (thus locking in your selected left hand), or select one of the OTS for this style and then freeze it. This would lock in the preset left hand indicated in the style. Both of these registrations are stored in user memory (and, of course, also stored on a floppy as backup). If any of the stored registrations refer to a style that is not a preset style, then it has to be available in user memory -- which, as we are all learning, is really a limited commodity. So discretion may be necessary in selecting styles that are not preset. This may not be as limiting as you might suppose. If there is a preset that is OK, but you don't like this or that instrument, you can adjust as you want and then save that "adjusted" preset style in the registration button. Then when you call up that preset style, it will be loaded along with all your modifications.
