You have to determine what you're willing to spend and how much you're willing to throw away. You can run a 8.5lb magnesium SSR Comp on the street but the first pot hole or road plate you encounter will make it look like a melted clock in a Salvador Dali painting. Tracks normally don't have those obstructions therefore it's safer to run a lighter more malleable wheel.
The lighter wheels are only that light b/c they go through a much more intense manufacturing process. They are typically designed for strength and that allows them to be lighter. A 14lbs rota will fold over WAY before any 8.6lbs Volk wheel would. Its a much more costly process to make and I am sure its a much higher quality metal as well. A real forged wheel should have no problem against a pot hole.
