Would you rather?

So here's what happened, best as I can piece together.

Brian Boyle smashes Rob Niedermayer into the sideboards. Travis Moen skates in to hit Boyle, but is quickly pulled aside by Tom Preissing. Niedermayer comes up swinging, but is wrestled down to the ice by Boyle. Your typical BoC get-together.

Here's the announcer: "Anaheim penalties to #32 Travis Moen, two minutes for roughing. #44 Rob Niedermayer a double minor, four minutes for roughing. Los Angeles penalty to #22 Brian Boyle, two minutes for roughing. Anaheim has the option of playing two men short for two minutes, or one man short for four minutes."

First question: Has anyone ever heard of a coach given an option of how they'd prefer to serve their team's penalties before? Is that even textbook legal, or just something that sort of got slipped in the heat of game action?

But now that it's happened, here's question two: if you were a coach in that situation which option would you choose? Both seem likely to yield a goal, so I guess the question might be which is more liable to yield two goals? Randy Carlyle opted for the 4-minute 1-man-down option (which I think is the correct call the referee should have made), but what would you take as an overpenalized choose-your-own-adventure coach -- two minutes of 5-on-3 or four minutes of 5-on-4? Theoretical answers are welcome in the comments.
