If you're looking for a fruit beer, Bloodline probably isn't for you. It isn't sweet or mild. If you want a fruit-influenced IPA along the lines of Stone's Grapefruit Slam IPA, however, this is an excellent choice. Like all of Flying Dog's beers that I've had, it's fairly strong (7% in this case) but very well-crafted, with enough body to offset the significant bitterness. The orange is subtle - if I were tasting blind, I might not even notice it. It adds a slight fruitiness to the bitterness of the hops, and I like it a lot.
I think Bloodline is seasonal, so you probably won't be able to find it for long. If you drink a lot of traditional American IPAs, this is worth a try for something just a little bit different.
