I like the above info. If I were to fruit an IPA, id go citrus (orange, grapefruit, tangerine), pineapple, mango or apricot. It would be a fruit that enhances the hop character. With my experience with a peach beer, it turned out mudded. I'd go apricot instead, because it's more acidic with a similar flavor.
I would also showcase hops that are similar to, or compliment, the fruit involved.
I don't know if I'd ever fruit an IPA, but that doesn't mean that I don't like it. I am really digging Ballast Point's Pineapple Sculpin right now!
