I'm one of the persons who would love to see climbers classics. IMO the fact that the number of big favorites is what makes the race interesting. The this years lombardia for example. Many teams will work until civiglo is reached, because from there on pure climbers and classic specialists both have chances. Now lets say they do a real high mountain stage with numerous mountains. Everyone knows that at the end the best climber wins, or maybe someone like Valverde who sprints very well but thats already very unlikely. Trek would have Mollema but no reason to work for him, Jumbo has Gesink but no reason to work for him, Garmin has Talansky and Martin but no reason to work for them,... But what will they do then? Well I think that would mean that second tier riders would go early because they know that they don't have a chance against Froome, Quintana, AC, and maybe Nibali and Landa. Moreover such a race ofc. has to be hard enough that it can't simply be controlled by one team over the whole distance. Take this one for example:
Okay that one is maybe a little bit overkill, but do you really think on such a stage the sky, movistar, astana and saxo train will easily roll over the stage and it will come down to the final climb? I don't, and thats why would like to see how such a race would unfold, at least one time. Maybe it would be lame but I think it would be extremely entertaining (however I see the point that pure climbers already have gt's so they don't really need classics too, I just think the racing would be good)
