I'd take issue with "younger and classier" tbh; there is very little difference between the GN profiles of Hedgehunter and Mon Mome. Both debuted at 8, won at 9, went on to run the race of their lives to be placed in the Gold Cup the following year and headed to their third Grand National heavily weighted but not badly handicapped. Hedgehunter came second and I'd be surprised if Mon Mome is unplaced. He certainly has more chance of winning than Big Fella Thanks in my opinion.
Regarding the Gold Cup run, I'm of the opinion that Mon Mome's distant third was almost as good a performance as Hedgehunter's close second in a much weaker race.
I'd agree with every word of that.
I think Mon Mome to place is probably the best bet in the race.
