Great summaary!

When you put it like that, it almost resembles having a classroom of kids with different personalities and talents. Some are thoughtful, some creative, some quick in execution. You choose wisely the path each takes and allocate tasks accordingly. Gives me chills to think of it...

Those distinctions make sense. I guess I'm more interested as to "when" you make that decision. What triggers you to spend the cognitive energy on deciding which model?
