Indeed, he can't be touched, his fall having taken place too far out.
Currently on 146, they might want to get him up a couple of pounds if Aintree is on the agenda. I don't think they'll want to be sweating about making the cut leading up to the 48-hour decs.
Whether he can afford to win a lesser race now is maybe open to question. Winning the Hennessy, given its value, was maybe a gamble worth taking but the world and his wife will be interested in Remastered when he next appears.
They'd maybe prefer to place in a decent race, go up to about 148/149 and maybe win something like the Eider after the weights come out, when he can't earn a penalty.
Interesting enough in his own right, though.
