Have you found any varieties that taste like the parent poster describes? I.E. with heavy corn flavor? I've tried a few "heirloom" varieties and they've usually been nuttier-tasting, with smaller pops and a much worse popped-to-unpopped ratio than the Redenbacher corn (though the flavor's usually interesting enough that I don't mind that too much). Definitely not cornier-tasting—farther from it, if anything.
