FWIW, the lauter efficiency for a no-sparge that thin (5.9 lb, 8.5 gal) will be ~88%.

The 2-3 qt/lb range will work perfectly well for a mash thickness. I'd wager to say you may even see a bit of an efficiency boost. Don't be afraid of a thin mash.

So I don't need to decrease my efficiency for no sparge?
I am a great believer in luck, and I find the harder I work, the more I have of it.

You do, but it becomes negligible for a beer this small. The no-sparge lauter efficiency is 88%; for two equal runnings it's 91%.

It actually should be if you get every last drop out of the tun.

Conversion will be slow, and potentially incomplete if you no-sparged this one. You're up over 5 qt/lb if you mash with the full volume, and that is thin enough to cause issues in my experience. If you mash and sparge with equal proportions of liquor, then you should be in a good spot.

That would definately be easiest.  I was originally worried that doing it that way would cause troubles because the highest ratio I've ever done was 2quarts/lb.  I haven't really learned about affect of thin mash on ph etc...
