The typical IPA I brew is about 5.5% ABV and 50-60 IBU. It may or may not be hazy. It may have no Crystal malt, or it may have 5-7% of any Cara malt from C-15 up to C-80. It generally has about one metric sh*t ton of late hops/dry hops. Is this an IPA, an APA, a Blond ale (if you've had Eureka from Tree House, you'll understand what I'm talking about), or something else? I call them IPA's and tell my friends that's what they are. I doubt many would qualify as an IPA in a competition, though.
In my book (which means nothing), if you added the crystal, it's an APA. If not, an IPA. But at 50-60 IBU's, it would be (has to be!) well out of Blonde Ale territory. Though I get your point about Eureka. Treehouse just doesn't seem to play by the same hop rules as everyone else. ![Smiley :)](http://www.homebrewersassociation.org/forum/Smileys/default/smiley.gif)
I do think a late addition of a metric s#!t ton of hops is fair game for both APA and IPA. So...you aren't making anything that you specifically call an APA?
I come from a time when Crystal malt was allowed in IPA's

, so that's not a determining factor to me. And to that point, the only time I brew anything I call an APA is when I get nostalgic for APA's from 20-30 years ago from breweries that have long since gone away. They definitely have nothing close to the hopping rates that I use in my IPA's, or even most modern APA's.
