I've backed 6 so far and rank them in the following order as to their chances.
Panda Boy 2ptew 16-1 B365 & 27-1 Bex
Meetingofthewaters 4ptew 15-1 WH
Adamantly Chosen 1ptew 66-1 Betvic
Galvin 2ptew 22-1 WH
Mr Incredible 1ptew 25-1 B365
Chemical Energy 1ptew 25-1 B365
I have Kitty's Light on my to do list also but have held off for now on a class thing - and I'll no doubt add more...
Also done the related double on Meeting and Panda with The Goffer in the Topham (no idea if he runs in the race but would like his chances if he did and he looks a non stayer for the big one)
I don't think you need to stay as much as you think but you certainly need stamina after the last.
Big worry would be Corach but I might just cover him for my stakes nearer the time.
Have added another 2ptew 16-1 Meetingofthewaters and another 1pt Panda on exchange.
cashed the Goffer doubles and added 1pt at 150+ on exchange as looks more likely Gordon will send him to the big one. Can always add again if he lines up in topham that the lizard is going to win anyway

layful:
And with Limerick Lace looking like running also have added 1ptew 25-1 on her.
Kitty's now in the team also 3pt win 16-1 B365.
So that might be it until final decs 9 is enough I reckon.
Fairly confident that Meetingofthewaters if declared will be close to Fav and has an outstanding chance. Which means Panda Boy has also
(been a random drift on him today and the top 3 have all shortened)
I do fear Corach still, and Maximus and Vanillier but will have to be against them I think if the prices stay wrong.
There is reasonable arguments against all three at the prices, as they are all not that well handicapped and aside from Corach the other two have jumping issues. Certainly not armchair rides anyhow.
Have had 2 x 0.5pt doubles the other day with Nick Rockett and Corach/Noble Yeats, so hopefully he does the business Monday and I'll have 2 course specialists covered before the day for little outlay.
