For years I routinely used crystal malt in pretty much everything I brewed, even pale ales and IPAs. I don't like a bone-dry beer, so I figured crystal would keep things a bit sweeter. But the last several APA/IPA batches I've just gone 100% base malt, and they have been phenomenal. I mash around 152 for most of these and they are slightly sweet and just great... I never realized that I didn't really like the flavor contributions from crystal malt. I'll still use it in some styles (ordinary bitter is one I do a lot), but I'm leaving it out of more and more beers and pretty much never regretting that.
(I do use a little Munich when I want some maltier flavors.)
