Angry Beaver double batch brew day

I've been looking forward to today for about a month now. I will be brewing 2 separate beers, 5g of a RIS clocking in at 17.5% and 10g of an amber ale that gives me an erection every time I drink it. Anyone have tips on how to make the most of the time?

I just did something like this a couple of weeks ago. What I did is as soon as I was done mashing and sparging the first beer, I had the strike water ready for the next beer. Cleaned out the Mlt and doughed in the next beer. By the time the mash was done for the second beer I drained the kettle into a spare turkey fryer pot with my IC in it to start to cool it. Only added about 1 hour onto my brew day.
