My mind has been blown. 100g weight difference relegates these to the flats with a sprint finish? What??!?
I was giving an example (or the only example) of when a 404 would be a better choice than the 303. It has nothing to do with the 100 grams, but the marginal improvement in aerodynamics and rear wheel stiffness. You can ride a rear disc as your every day wheel if you want to, but that doesn't make it a practical choice. In other words 303 > 404 for everything except that long, flat race with the sprint finish.
