I would think clustering. I tend to try to find a shallow area that has access to deeper water, and is close to my CNBG spawning area. To me, that's a triple play.
I also put them out in areas I feed. I've noticed that some of my fish will move into an area just before feeding, then move out of that area once the foods all gone. I'll position my feeders this year to the areas that they naturally roam. Kind of like home delivery.
