It would be interesting to see where the Lupo 72 falls on the Karve Plate lottery. Not just equivalent efficiency, but some of these other characteristics that have come up, which provides the best balance for you. Blade feel wise, I bet it matches up with the Karve E, but as far as actual efficiency and aggressiveness, that's an open question. Also, the Karve C vs the Lupo 58 seems like a fair match.
