I thought I'd love this being a big fan of both Campari/Italian bitter red and grapefruit juice, but the two of them very effectively neutralize each other, creating something far more mild combined than either are on their own. A waste of Campari.

In the Manhattan vein but fruitier and less vapory, the Chambord adds such a nice change of pace, and plopping in a few fresh home-made Maraschinos went a long way. Would be a nice after dinner and/or dessert drink.
