I use a 48 qt. rectangular cooler. I make 5 gal. batches, usually with 12-17 lb. of grain. I lose maybe 1-2 F over an hour mash, so I don't think you need to wrry about losing heat.

Trade off is a higher amount of dead space though that can effect efficiency.

You're gonna have to explain that one to me. I've used a rectangular cooler for 426 batches now. I have no dead space and on yesterday's brew got 86% efficiency onto the fermenter.

i use a 36 qt cooler to split 10 gallon batches with a friend. The other day i did my first 5 gallon in it. Terrible efficiency, in the 60s! Could be due to dead space AND/OR the fact that I was using Mesquite pods as some of the grains so my grain bed wasn't much of a sponge. It floated up with water as I was sparging. We'll see what a 5 gallon of only grains looks like

70 Quart Cooler... going to probably just brew-up a 5 gallon batch... Is the cooler too big? Will I have a problem with the grain bed?

I fit 85.5lbs of grain with almost 30 gallons of water in a 150qt cooler! The only problem with that is moving it and dumping it:-)

So when batch sparging, all the stuff you read about the grain bed being at least so many inches and no more than so many inches does not matter?
I'm asking because I have a 48 qt rectangular cooler that is very clean that I could use to build a lauter tun, but I am afraid that it will be too large since I am only planning on 5 gallon batches with OGs in the 40s to 50s.

You shouldn't have an issue, many on this forum use that exact setup.
