I own the sexy spades medium but to be honest I wouldn't get any of them. The spades, and the moon plug also (so it would appear), seem to have more girth in the body of the plug than the base. Being an overly cautious fellow, these toys seem too easy to lose, especially if your more of an experienced anal player and can relax easily. This is also the reason my sexy spades doesn't get much play. Out of all of them, though, I'd go with the medium spades...it really is a pretty plug.
