Aneros and Weed

I've seen how weed is consistently mentioned as one of the best tools to help you get to the Super-O, but nobody mentions many details. So say you were in Colorado, where weed is legal. How much weed would you smoke to use the aneros, just a puff, a whole bowl? Would you smoke before or after insertion? Would you smoke indica or sativa?

Feel free to mention other little details about getting there. I've often wondered, for example whether it would be better to be well rested and energetic, or to do it post work-out.
