why you have to be stereotypical and collectively group all the different IPA's that dogfish makes as overrated but I happen to really enjoy their 90 minute. It has an awesome malt sweetness blended with the hop bitterness.
Noteable IPA mention that I think is widely distributed:
Weyerbacher Double Simcoe
Flying Dog Snake Dog and Double Dog
If you want to take the IPA training wheels off and go with a solid kick in the teeth, give some agressively hop'd American Strong Ales a try. Stone's OAKED Arrogant bastard is quickly becoming one of my favorite beers. Or slightly more mellow but with an amazing smell try Troeg's Nugget Nectar, it is an imperial Amber that could easily be confused with an IPA.
