Heppell Vs Duffield

[Magic 7]

I was just wondering who should I choose, Heppell or Duffield.

It's tough one, I have Heppell atm, I reckon he's in for a big year through the midfield. Duffield stats are great, he always concerns me with his consistency for some reason. I'd opt for Heppell, but it really is a gut/opinion one.
