I run 215-40-17 direzzas and I have found that they get greasy for me when I run them. I spray them down between every run now and they are much more consistent and predictable. I love them, but they do get greasy for me. I haven't used any other tire though to compare them to. I'm new and I'm sure I am over-driving them though, so it may be as much me as the tire to blame. I've finished 1st in STN at every event I've raced in and I've had a 1st and multiple 2nd and 3rd place finishes in GS, and I'm sure these tires are a big part of that.
