It was more or less certain Trobaniello couldn't be a stage finish. I would definitely prefer Pola de Somiedo to a San Lorenzo MTF though. I think San Lorenzo is a tough enough climb when used as an MTF that it would affect how Trobaniello is raced - although Trobaniello could be preceded immediately by Cobertoria East, and leave us with an absolutely epic triple-ESP stage that traceurs have been hoping for for years.
I would add that the climb to the castle in Burgos isn't that much of a climb. You put a 35-40km ITT, you basically have 33-38km of pure power test with a couple of punchy but not overly steep kilometres at the end... I think that would be a good TT actually. The Castillo isn't a super tough climb that will make big differences to the TT times; yes, one time Purito won there. But this year Juanjo Lobato won there. It would still be a TT for the specialists, and only offer the merest of carrots to the non-specialists to try to win back some seconds.
And it may encourage some riders targeting the Vuelta (which there will always be more of come late July than there are at this point, due to riders getting injured during the season, crashing out of the Giro or Tour, etc.) who normally wouldn't to ride the Vuelta a Burgos to check out the roads.
