Englisizing The Paper

I'm in editing mode. Lately, I've been working with a couple of coauthors who are very, very good theorists. Their game theory/math chops are so much better than mine that I try not to discuss it. In addition, one of them is very connected with the top people in the accounting area (he was the other's chair, which is how we met).

They just dropped about a 40 page current version of a paper we've been working on for quite a while. The logic of the paper flows soundly, and the empirics are solid.

Unfortunately, neither of my coauthors has English as a mother tongue. So, I'm in charge of "Englishizing" the paper.

Oh my!

Update: I may have given the wrong impression (at least, based on a comment by Bob Jensen). My colleague and I have been working on this paper for quite some time, and we've all been involved with most parts of the paper (with the exception of the game-theoretic part, which is admittedly not my strength). My contributions have been primarily in the designing of the tests (my colleague is a game theorist, not an empiricist) and in the final editing of the paper.
Since I did my early education at Our Lady of the Bleeding Knuckles Elementary School (and yes, they did use the curtain rod), I received pretty good training in the fundamentals of what I call the "micro" part of writing.
