Yeah that's what I did. After reading through this thread and some others, it seems like a lot of people are doing in-your-face hoppy beers like that now. I brewed up another batch and added a 15 minute addition to get some more IBUs, so we will see how that turns out.
Yeah, usually best to follow the recipe as written first. It's popular for a reason. Then modify based upon what you are missing.
Also, how long have you had this in the keg? I've found the the flavors really blend at about 2 to 3 weeks in the keg. Before that, they are there, but kind of stand alone and in your face, if that makes sense.
