It hardly seems worth the trade-off. The more exhausted I am at the end of the day, the less inspired I am the next day. And trading two (experienced) developers' time for a rare chance at an epiphany doesn't seem worth it, either.
I meant that it was rare to find a pair that you function like that with. If you have two senior developers who can do this and are not letting them pair, you are introducing serious amounts of waste.
