I don't know what the black art of tool selection is, but I'm at least a couple std deviations above average on picking libraries that have legs. Nobody gets it right every time, but some people seem to get it wrong every time.

Be sure the work is given to someone who puts some intention into tool selection and you'll probably be okay though. We don't need three different tools doing the same kind of tasks. But sometimes the old old stuff gets moved to the new tool because the old tool couldn't handle that scenario.
