Where the GN is concerned, I'm prepared to overlook a string of "disappointing" runs before the weights come out.
My gut says if the jockey genuinely felt it didn't take to the test last year he'd have said so to the owners who must have plenty of ammo for it when you consider the size of their operation.
Won the IGN, then ran over hurdles until after the weights came out and failed by less than a length to give weight to Nick R who was already rated 10lbs higher. NR, of course, wins the GN.
This season they've kept it to fences. Have they felt it an urgent matter of getting its weight down? 157 in the Hennessy, 155 at Chepstow - two "disappointing" runs in the UK in full view of the UK handicapper - and now it looks like it might get into the National off 148. They probably weren't expecting that.
Even if it doesn't win the Eider, it might only need to show that it is "coming back to form", "is a 'spring horse'" or "we discovered some minor issues with him and tweaked a few things"...
Edit to PS - I've just seen that Nick R was made 9/1f for the GN last year after winning the Bobbyjo but his SP for the race was 33/1. It's a funny ol' game, Saintie...
