Yeah it's a tough one - I was leaning towards Inglis myself more because of his capacity to add bonus points via his keeping, which could be quite lucrative especially if Fawad and Agar are on their games and he can sneak in a stumping / catch or two off them.
Weatherald probably has the higher scoring potential with the bat at home given his ability to reach or clear the boundaries in bunches in a hurry and he's probably due for a decent hit out.
Still up in the air at the moment but there's 40-odd minutes to work it out..
