Personally, I like APA to have a little more malt character,ie., to be more balanced than IPA. I blend the 2 row with ~ 20% Munich, Vienna, or MO for APA. I also use a little more crystal for APA, ~ 7% (as opposed to no more than 5% for IPA). As for water salts, I use gypsum to bring out the hop character, but I don't try to get the beer as dry as an IPA. Definitely not a smaller IPA to me.
