I think that when IPAs/DIPAs are done right, there's really quite a few of them that are on the same playing field. Just my opinion. The thing that makes me prefer a Pliny over say.... a ST 2XIPA, is that the bitterness lingers and the flavor sticks with you longer. Some of these newer citrus forward IPAs... (2x, Perpetual, White Raja) just don't have enough lingering hop flavor. The aroma and initial hop-bite are there, but the finish is lacking. If that makes sense?
