I am not a fan of serrated blades, but the OHTs blade doesn't bother me much. I don't use it for hunting, as I have the Vic Hunter lockblade that I've used for game chores.
With a plain edged knife, I am more inclined to use the back of the edge to unzip the animal anyway and the tip for the finer cutting chores. I gotta say though, I don't believe that the shallow serrations on the OHT will hurt your ability to perform your game field duties. You might want to go slow till you get the feel down.
BTW, I'm slowly sharpening the serrations out of my blade, as well as putting a second bevel on the edge.
