Adding Gamoniteiru to the Vuelta is something I am 100% in favour of, even if it's another of those Vuelta "add-another-mountain-wooo!" approaches. Best addition to the race in some time, and with the promise of a similar stage to 2006 before it, it certainly has me intrigued - could be a real queen stage with a couple of climbs before San Lorenzo, Cobertoria, then Gamoniteiru via Cordal. That could be a real, genuine, proper mountain stage, of the sort the Vuelta has been lacking.
However, if they do do that, then I am dead set against Angliru the next day. They'd just be repeating themselves. After all, Angliru stages are pretty much one-climb stages, sure, but the climb is tough enough for that not to be a problem. But Cordal is the nearest thing of any significant difficulty that they could put into the stage. The only ways I can see them satisfactorily reconciling the two without repeating themselves are:
1) one of the stages is much flatter than anticipated;
2) one of the two stages is an MTT;
3) they forgo Gamoniteiru and go with a hellish queen stage doing San Lorenzo, Cobertoria, Cordal AND Angliru, or descending Cobertoria via the Cordal route to Angliru.
All three are disappointing in different ways. 1) because it would involve a disappointing stage (but is most likely as it would fit with Unipublic's recent themes), 2) because it's least likely by a long way, and 3) because it would miss out Gamoniteiru, the inclusion of which is one of the main reasons for excitement about the pronouncements.
