I've been doing my first few AG's by following John Palmer's methods in How to Brew. He stresses to add preheat the MLT, and then add the mash water to the grain -- not the other way around.
I've seen quite a few folks here preheat their tun with 180º water and wait for it to settle to strike temp, then add the grain to the water. That seems easier...but I can't find any information as to what the pros and cons are for each.
