I have been using them this year and so far they have not been a problem in the WB on my bow but I have shot two animals with them 1 deer and 1 coyote. After passing thru the animals they completely ripped off and made fiinding my arrow very hard. I am going to be getting a flethcing jig and fletching my own arrows next year after what happened. I was lucky to find my arrow on the deer I shot, not that it mattered because I seen him fall over. Just the thought of not being able to find it makes me worry.
