The big question would be, who does he learn from at Lampre? Even at Caja Rural, you've got somebody like David Arroyo with a wealth of experience in top teams and at least at a reasonable GT level (the 2010 podium aside, he's still made Giro top 10s on multiple occasions) as a pure climber with little in the way of TT capability (I nearly said no rouleur skills, but he used to do 'cross and that skill came in very handy in Montalcino, plus of course he's an amazing bike handler, you have to be to descend like that). Lampre have Rui Costa who's not really the same kind of rider as Hugh, and Niemiec who may or may not still be there.
Plus, Louis Meintjes is probably Lampre's climber for the future and even if he, like most "expansion region" stage racers is going to want to target the Tour, I wouldn't be surprised if Lampre would want an Italian leader for the home race.
He doesn't need leadership roles any time soon - but he needs maybe a bit of a free hand. Places like Sky and Movistar he'll be hamstrung by the strength of those teams in depth and maybe not get the freedom, Sky could roadblock his development due to sheer numbers of big names, and Unzué may well slow his pace of development owing to his traditional caution (plus, Rubén Fernández and Marc Soler would probably be ahead of him in the queue there). Most of the WT level teams where he'd have the freedom he'd not have any support - Giant, Lotto and so on. Orica might be a better bet, and I never thought I'd be saying that three years ago. But they've got their youth phenom already in Robert Power. Maybe even the French teams would be best - somewhere like Cofidis or Ag2r - but then like Lampre there's not as much in the way of GC experienced older riders to learn from (except Pozzovivo I guess). And then, the question would be, will he really be better off riding the hilly and rolling French one-day races than he is riding the Spanish short stage race calendar with Caja Rural?
It'll be interesting to see what move he makes next. I certainly won't be surprised if Caja Rural are very keen to lock him in for another year or two, then at 24, if all goes well, he'll be an established prospect ready for a good contract with one of the biggest teams, and Caja Rural will have got some useful exposure out of the racing he's done for them then. But if he continues to race like this, they might not be able to afford to keep him on on their budget. I mean, they had to let Omar Fraile go this year, and for a team based in Navarra having a very talented young Basque rider is kind of their thing.
