This would be very close. I know both are skilled wrestlers, so it would require a lot of effort to get a prolonged tickling advantage on the other. I'm sure both are very ticklish, and from their personalities I would venture to say both are far more likely to be ticklers than ticklees. Therefore, tapping out would be something both would be very reluctant to do. However, I see Sarita tapping out after a loooong tickle match.
