I was looking into rebuilding my wheels. I am interested in bladed spokes. I know some elliptical or bladed spokes require flange filing. I do not want to damage the structural integrity of my Dura Ace hubs though. All of the threads I found with info about this topic were archived and very old. I was wondering if there are some spokes now that don't require filing. If you have some pictures of stuff you find or of your personal builds, please post them.
