I think you're right. Now I'm speaking as someone who barely has his toe in, or should I say barely has a whisker in, and has no expectation of participating at those new levels. But I doubt very much that the level of artistry and customization that I've seen here has ever been approached, or as widely done, in the past. Not to mention the scientific and technological resources that I see people bringing to the fine-tuning of the blades.
