I doubt this sort of instability could be overcome by fletching with feathers.

The center of the Blazers barely moved in any direction more than inch during the whole flight. It was the front that was swinging back and forth from getting caught in the wind. I think the Blazers actually did a great job stabilizing the broadheads enough to impact straight but to the left of the target for how much they were moving.

Plus, I've wanted to try the Wac'ems since I saw and read about them.
