definently gota watch them! i almost ended my season sunday. i was shooting in the backyard..i thought i nocked the arrow but i must not have..i was to busy on thinking of better shots to take i havent tried yet..but i pulled back..arrow swung around and layed on my arm!! now..the tricky part..how in the world do you let down to fix the arrow when the broadheads laying on your arm!?!?! i somehow got it off but if that head wasnt dulled from being shot 100s of times it would been BAD...
