Try Olympus X Laserlight (or any red/white). It only has 3 (or 4) possible outcomes: Love, Olympus, Laserlight, and Prime Power. Sadly, there is no way to get rid of the 15 hr. Laserlight fails.
Edit: and maybe White Chocolate is another possible outcome now? Can't tell if it is breedable or just on sale. :/ It's a 15 hr, too, though.
