I don't have the latest Frankenjura guidebook edition - don't need it, am in little danger of running out of things to do in the 2009 edition that I have - but iirc there are something like 50 9a's in the area, of which Herr Bock is the FA of all but a handful.
Has anybody else (a) put up that many routes at that level, or (b) monopolised hard first ascents in a major climbing area to such an extent for such a long time? The other example that springs to mind is another German one, Toni Lamprecht at Kochel, but Kochel isn't by any stretch of the imagination a major destination like Franken.
