Mainly from smallblind, but it can also be done from final positions depending on many other variables, of course.
Everything in poker is about risk benefit.
I believe that the important thing when you raise with aces is to play with the least amount of opponents (heads-up preferably).
Because we are so far ahead, I believe we can do this, but as we see aces being broken all the time, don't abuse it or keep in mind other relevant factors such as tournament stage, stack, information about opponents, etc...
