From the sounds of it I'd suggest going for the small, since you don't have that much alone time to possibly use the knot of Medium Austin. Austin's knot is more gradual than most so I think if you had the time you could get Medium Austin's knot in, but you probably won't get the chance. That being said if you're going to be moving or something else will be happening later that gives you more time alone you might want to consider Medium Austin for the long term. I'd imagine you don't want to end up having the same toy in 2 slightly different sizes, but you tell me.
Oh, and because I think it depends I won't vote yet.
