I'm planning on serving one pitcher-type cocktail at a casual pool party. (One pitcher to be non-alcoholic). I'm planning to make it from lime juice, simple syrup, and purreed watermelon (garnished w/ mint and honeydew balls). The recipe I'm sort-of using calls for tequila, but I'm wondering if rum or vodka would be better. I would prefer the least potent if there is a difference.
Any other hints would be appreciated by this wino who knows nothing of cocktails.
