No need to argue. 🙂 There's math to understand exactly how much time you'll save with less weight and with less aerodynamic resistance, so you can know which is more beneficial and by how much. We all have so much ride data we can break down how hilly our riding is, what % of our miles are on different steepness ranges, etc, to help with the "for most riding" part. You can even do that for just got favorites. We live in a golden age of cycling.
