I don't know if anyone is actually talking about bolting anymore in this thread, but I would recommend that you go out and place a few in some rocks that aren't going to be seen or climbed on. It's good practice to use the drill before hand, because that heavy mofo can go in lop-sided pretty easily.
More advice? Choose a flat spot of rock to place the bolt.. there can't be any cracks around it either (you don't wanna pull the whole piece of rock off!) and I have used a hammer to flatten any nubs (haha nubbes) around the area, so I can get the hanger to lay nice and flat and not spin. I doubt this affects the strength of the bolt. The hangers are all "unidirectional" are they not (they have the same shape, there's no left and right hand hangers, I think?) so they should lay the way they hang, I think. On perfectly horizontal roofs you need to consider that a normal hanger might put leverage on the bolt, so there are hangers (I think) that are better for this.
I dunno, I could be all wrong, and I could be repeating, and I could be too late, but those are some of my tips for bolting! (Though I've rarely done it).
Bouldering is a dish best served cold.
