Rather than multiple colonies of the same culture, I prefer multiple cultures from unique sources - each with different flavor and leavening profiles.

Bill, do you archive these in some way, such as by freezing? I wonder if they maintain their unique natures, or if, during maintenance, they evolve to be more similar.
I maintain 4 distinct starters in the fridge - all purchased from sourdo.com. Most of these have been used in commercial bakeries for a couple of hundred years and are prized for their flavors, leavening power, and resistance to contamination when properly maintained.
The conventional wisdom that all cultures eventually devolve, overcome by stronger local strains, applies IMO to weaker, more vulnerable ones. The starters from sourdo.com that I have used for over 7 years have maintained their unique characters. They are "strong like bull".
Out of an abundance of caution, I never have more than one culture out of the fridge at a time - not out of fear that one may launch an aerial attack on the other, but to avoid a stupid mistake on my part.
