As a dedicated (addicted?) ice-cruncher, I prefer the wimpier ice cubes. I have at least as many different descriptors for ice as eskimos have for snow
I hate the hard cubes, but love the slushy granuly ice from ice machines in restaurants. My favorite kind, though, is a very aerated ice cube that is split and results in a yielding texture that just about melts as you crunch it. Perfection. Mmm....
