Head to head, I'd say:

Foden > Hook as a Fullback, although Hook is a better player.

Ashton > Stoddart

Tindall < Roberts

Hapes < Davies

Cueto < Shane

Flood = Jones

Youngs > Phillips

Sheridan = James

Hartley < Rees (Though not by much)

Cole > Mitchell

Deacon < Davies

Palmer < AWJ

Haskell < Lydiate

Wood < Warburton

Easter > Powelly

5 for England, 2 drawn, 8 for Wales. I may be slightly bias (AWJ>Palmer, Lydiate>Haskell, Rees>Hartley, ect. could go either way, dependant on your viewpoint) but I'm saying that may well reflect in the scoreline. Hopefully. C'mon Wales!
