I don't think I agree with no comments in methods and not much comments overall. What if the comments specify why you're taking a certain approach over another or something that was decided by other people? Comments are good for documenting not what the code says, but the reasoning behind that code. This is especially helpful if you haven't looked at it for awhile.
