Barrett,
From what I've gathered from the persons who flew with the Gallands, they agreed that while Wutz was the better fighter pilot, Dolfo was th better combat leader - in fact the best combat leader they had. As General der Jäger, Dolfo was at the heart of German air developments and while he certainly didn't think of everything himself, he supervised or directed or was at least involved in many important developments that have had some effect in aviation. And after the war, he and a few others (Baumbach) organised the Argentinian air force. When the Falklands War erupted, the Argentinians still relied on the tactics and doctrine as laid down by Galland - and to some good effect I've heard. Add that to his record as a fighter pilot (during the final stage of which he was also heavily involved in developing jet tactics, like firing rockets etc.) I think I would have to nominate him for a high position.
My top 5 aces would at this moment be:
1) Boelcke
2) Galland
3) MvR
4) Marseille
5) Hartmann
Yep, all Germans: I don't know enough Allied ones to make a decent verdict!

Besides, I doubt many will question my choices here.
Kind regards,
Reinout
