My favorite IPA's these days are also in the 6-8% range, and favorite hops are Citra, Mosaic, and Galaxy, when in season. I must admit, I do like the lactose/oat cream stuff, though not necessarily any more than without.
Downtown Crown gets Other Half beers from all three Other Half locations. Dominion only gets Other Half beers from the DC location. Some Beer Advocate people report that the DC brewery doesn't have things as dialed in yet as the other two do. I haven't had any of the DC IPA's so can't report (did have a DC Other Half Crunchee/ Burley Oak JREAM hybrid fruit beer collaboration that was very good.)
