I hear you. One of my core principles is, "do it right, and you only have to do it once." I always overprepare, because then I have more of a buffer built in when something goes wrong that I didn't prepare for - and you know that's going to happen at some point in every run. There's no such thing as being too prepared.
Welcome to the boards. Just please don't kill Vostok; I like him. Every time he types "moose and squirrel," I fall over laughing.
