Yes, I use them. I like them in lightly hopped ales as a bittering and late addition as they give a bit more of a twang than a cleaner bittering hop, for example, in barley wines and golden ales. In more heavily hopped ales I like them as late additions, where they give some good dark fruit and blackcurrant flavours (try a single hop pale ale). I've got mixed results when dry-hopping with them as they aren't the most pungent hops out there, but they definitively do have an American character to them. They would be ok in an IPA as part of a mix of hops, but wouldn't stand out to Simcoe, Citra, Amarillo or other modern more heavily flavoured hops. One of their positives is that they barely have any of that grapefruit / citrus flavour, so you can highlight more floral or dark fruit flavours using them.
