Reminds me of a pair of cognitive scientists I know who often collaborate. One is expansive and verbose and often gets carried away on tangential trains of thought, the other is very logical and precise. Their way of producing papers is the first one writes and the second deletes.

That's a great model. Even if you're not naturally that way, it's helpful to think of a verbose phase followed by a revising phase. You can do this either as a team or as an individual—though as an individual it can be hard to context switch.
