    Doesn't 13/8 7/6 look more natural because less wasteful?
    Who would play 8/3 here?

    You're saving the gammon, so crossovers matter a lot more than pips.
    You're going to need three crossovers regardless.
    8/3 means you'll be able to get a crossover if you roll an ace.
    Ensuring you can get a crossover with an ace is a common theme
    when it comes to saving the gammon.
