Time for Rupert?

Hello all, first time I have posted here. I was casting my eye over the Gold Cup, and seeing Time for Rupert entered, I must admit, initially I dismissed him as not experienced enough for such a big  step up. However on further reflection, and accepting he is more likely to go for the RSA, I believe he would not be not such a no hoper for the gold cup as his odds suggest. I don't think Kauto or Denman can win it again, given age and probable decline. Imperial Commander  cannot be dismissed as easily, but age is an issue, and he has been off a long time, although he is lightly raced and loves Cheltenham. Diamond Harry would seem to have much the same chance as Denman on Hennessy form, and his RSA run last year just puts me off a bit. Long Run must have a fair chance, only 6, but has had plenty of experience for a young horse, I personally just  have niggling doubts as to Cheltenham being suited to him. Pandorama seems best of the Irish, on his form in Ireland he can be well fancied, but he has yet to do it in England or at Cheltenham, his Hennessy effort was appalling. Yes, Time for Rupert would have to bridge a massive gap from Novice chases to a Gold Cup, but I think novices have won it before?, Little Owl springs to mind. He will stay the trip, right age, loves the track, and although he will have to jump fences quicker than ever before, you would have to think he has the class given last years world hurdle run. There are doubts, mainly being a novice, but there are just as many doubts surrounding the principles,  If he were mine (such a dreamer I am) I think I would take a chance and go for the big one, maybe it might just now be "Time for Rupert"?
