Because both usually involve sustained speeds in the mid-high 20s over flat courses with very little climbing or accelerating. They are designed therefore for aerodynamics at the expense of weight and bad at all the things you claim to like them for. Specifically the newest corima fronts are still pushing 900g and so heavier than all but the stoutest or ****tiest spoked wheels. Your claims in general make it incredibly clear that you can't feel **** about your bike. Since you're not using them for tt/tris why would you base your equipment choices on them? Why not sell them to someone who can actually use them in a win/win situation. Some poor racer gets a little edge and you'll look and sound like less of an ignorant ******.
