At 24 miles round trip, I'd prioritize speed slightly over comfort and puncture resistance. A 32-35mm slick-y tire with some sort of puncture protection that isn't too heavy would be ideal. 32mm Gatorskins come to mind. As mentioned, Speed Rides are comfy and relatively fast rolling but at 40+mm they are heavy and sluggish compared to a true slick. I wouldn't use them unless I'm not in a hurry. I'm very curious about the Hypers, though.
