Hitch, you're every bit as much of a Zonc fanboy as the Spanish supporting the Angliru. Of course national pride comes into it. Contador said Angliru was harder, Simoni said Zoncolán was harder. I know you were just trolling when you said Zoncolan via Sutrio is harder.
Craig - the Nebelhorn is likely an impossibility to include. They could however use the Fellhorn on the other side of Oberstdorf - that's 9km @ 9,7% climbing to the Bergstation, which is plenty tough enough (though the Deutschlandtour definitely needs to come back, there's a lot of great climbs in the Schwarzwald to use, like Oppenauer Steige and Kandel, in addition to the handful of alpine climbs).
Bavarianrider - why post Nebelhorn? I thought that all climbs were equal in difficulty as long as they had the same altitude gain and so therefore that climb (1089m vertical at an average of 14%) is less difficult than the Parador del Condor (1143m vertical at an average if 3,3%)?
Also, speaking of the Deutschlandtour, I submit this one for your consideration, though it is of course in Austria:
When climbing all the way to the top (the Deutschlandtour used to stop at 2670m iirc) that's 13,3km @ 10,7%, which makes it longer than either, and steeper on average than Angliru. Even in the shorter version used in the Deutschlandtour it was 12,4km @ just a touch over 10%. But, crucially, notice the altitude, being 1000m higher than either Zoncolan or Anglirú.
