i would have to say 6-7 on the scale.....maybe even more than that...but like you know , they are thick, so you might not always have a good clean shot, but at least you're seeing something...this 6-7 came from all of my hunts hunting in them...i think you're doing the right thing by hunting them for sure...i still say stalk through them or if youre going to stand hunt, find a good trail and set up just within the head and wait
