In this modern world, different drinks call for different shapes of ice. A Negroni or Scotch on the rocks can benefit big time from a single large "king cube." A Dark 'n Stormy or any other simple highball cocktail can be fancified with long "spear" ice. And while you're at it, why not dress up your kid's (or your own) lemonade with some cute cubettes? Yes, having a variety of ice options does help with presentation, but the right ice can also keep your beverages from diluting too quickly. Most importantly, ice cube molds are fun, and that's what making cocktails is all about.
