Maybe I'm soft, but Habanero Sculpin was too much for me. I like beers with peppers in them (Xocoveza, Hunahpu, Mexican Cake, Bomb/Bible Belt), but Habanero Sculpin takes it a little too far for my liking. A beer like that needs to come in 3 oz. bottles.
Grapefruit Sculpin, however, is fantastic. They're gonna be releasing it in cans pretty soon. The owner of one of the distributors I frequent told me that they're gonna make it a year-round release. Not sure how much I trust him, but here's to wishful thinking.
