I got some H rated Diablos - cheap. They wear fine. I almost never ride faster than 180 km/h. Highest steady speed I do is 160 km/h (motorway). Guess W speed rating is just Yamaha's safety margin. Though, I'm not heavy and neither is my pillon.
Most things done in a hurry need to be done again - patiently.
