For mine
15 Liam Williams (W). Was on fire in NZ, remains on fire. Hogg is an attacking alternative, but can be a bid dodgy in defence. Halfpenny if you want a goalkicker, but Farrell will provide that so HP not needed. Mike Brown as an outside bet.
14 Anthony Watson (E).
11 George North (W).
Don't laugh but some of the Scots might be in with a shot on the wings, depending on 6N form.
13 Robbie Henshaw (I)
12 Owen Farrell (E)
10 Jonny Sexton (I) - very injury prone though
9 Conor Murray (I)
8 Billy Vunipola (E). But you can make sensible arguments for Faletau & Heaslip
7 Sean O'Brien (I). But you can make sensible arguments for Warburton, and I highly rate Van der Flier.
6 CJ Stander (I) I'm not sure - depends whether he goes pure 6, or converts Itoje (E) or Henderson (I) into 6/locks for example.
5 Itoje (E)
4 Kruis (E) or AWJ (W) - who has refound some form
3 Would have said Cole (E), but if Furlong (I) keeps up his form he could be a major bolter
2 Hartley (E)
1 McGrath (I)
