Your analogy doesn't make much sense.

It makes perfect sense from where Im sitting.

By using techniques such as streaking on agar plates, and isolating the healthiest looking substrains, then fruiting each one individually to see what produces the best fruit bodies - then printing those specimines?

Sure, I suppose that would work to some degree. I thought we were talking in the context of MSI though.
IMO there is no real disadvantage to using a high spore concentration in MSIs. There are some potential advantages though.
There is a problem getting much actual competition to happen though. The spores that germinate faster have the biggest advantage. If you have a high spore concentration you are likely to have a good range of genetics germinating at about the same time, whereas if you had a lower spore concentration you might not have very many germinating at the same time.
I guess the whole thing is debatable, but if your interested in more competition then more spores is the way to go. I don't think you can really question that.
Optimally you would dilute the spores and spread plate or overlay them on agar and isolate monokaryotic strains, analyze those, pick various mating combinations, then analyze the dikaryotic mycelia from those matings, then test them on actual substrate, then chose master strains to use.
That's a lot of work though and if you have the time and resources to do all that you are probably going to use your advanced breeding program for strain improvement and would likely be interested in the commercial aspects of it. I don't think that there are too many people like that here.
> the best spores and hyphaes genetic makeup takes over the colony,
"Best" is a subjective term. The fastest growing spores and mycelia will out colonize the slower ones. That doesn't necessarily mean that they are better in any other way. They might also be faster on your spawn, but slower on the substrate or faster on agar and slower on the spawn.
IMO for MSI you can't go wrong with more spores. You'll have more genetic variation and selection pressures will result in better suited mycelia colonizing the majority of the substrate.
From what it sounds like you're going to have contamination problems the way you did it though.

Isolates would be like picking the best runners of the crowd.
I did not start the stupid analagy..
