Hmmm...this is a tricky one. Initial impulse was "Bratt, definitely". But i think i'm probably letting some turmoil with Laine overly influence what he can be when he's dialed in.
Laine definitely has the advantage as a pure goal-scorer. But i think there's a tradeoff in that with Bratt being the better playmaker, while still being no slouch as a goal-scorer himself. I kind of like the upside of Bratt in that regard, as more capable of driving the bus for himself and others, where Laine can drive things for himself and he can put away goals that don't require an absolutely top-knotch setup man, but it's not like he's incapable of making a nice play either. Laine's size is also an advantage. Makes him hard to stop when he's determined. But therein lies the tipping point for me i think. Laine's motor has, and probably always will run a bit hot and cold. Bratt on the other hand, always seems to play with a lot of pace and energy...and i like that. I think you have a more firm idea of the sort of consistency you're gonna get from him.
But i can definitely see the other side of this.
