That's a good question me ol plummer lover!
Guess what, I don't have the answer, I dont't think there is a Correct answer, but I'll guess. I honestly believe it's in all dogs naturally instinct to strike, and strike well. Yes some better than others. You only have to see in local parks how many various breeds will strike at a tumbling/bouncing tennis ball with perfect timing to see they all have it in them.
For me it's not the strike, (and yes it's obviously important to strike well if your using your dog to hunt), it's more of "Can this dog use it's gears well, and will it use it
