I'm gonna risk a dumb question here...
Five flats in two days is pretty amazing, no matter what tire. What caused the flats? Did you check the tire casing and rim to ensure there was nothing causing the problem (hold the tire against the rim oriented the same way it was mounted and match the leak to the location). I'm assuming none were pinch flats... that's not a tire problem. What were you riding through... lots of glass? Goathead thorns?
