I've dabbled in low gravity hoppy beers, and something just seems to miss the mark for me when I just try to brew a sessionized version of an APA/IPA recipe. I think there's just not enough malt character to hold up to the hopping level I'm shooting for. The next time I make a run at this style, I think I'm going to come at it from the American Brown Ale direction - something with a bit more malt backbone inherent to the style.
Obviously, it won't work with WLP001, but something like a Bitter or Belgian Pale Ale is another solid choice, since the yeast brings a bit more character to the party.
