I like the idea of bringing a platform to attack closer to the finish as it really needed the right composition of break to take it all the way from the Mammolshainer Berg in recent years owing to the fairly straight and wide roads from Königstein back to Rödelheim on the outskirts of Frankfurt favouring the bunch. Hainer Weg of course is a bit more authentic for the old Henninger Turm days, although the climb really isn't particularly selective. The most selective climbs in the Frankfurt conurbation are over to the east though, around Bergen-Enkheim, which has a couple of short and sharp digs, but would entail moving the legitimately selective climbs further from the finish since you'd have to traverse the city, with the Taunus mountains being to the northwest.
