XD I don't think it would be option B, but it could... I suppose. If they want. I was actually working under the the A option, although physically it would only be Greater Medium acting as Lesser Large, which would have orfice stuffing build upon that.
Yeah, I'll let that option B be availiable for those who want it. Option A is still the regular rule, though.
EDIT: Rather, Option A is how I was doing it, and will continue to do it. B is an optional that the player can decide.
