I haven' t had the same problems but 1 thing to be aware of is that the blades close whether the arrow backs out or blows right through. They always open in the deer. The act of pulling out closes the blades completely and due to the release of pressure when coming out the far side of the deer .. the blades spring closed as soon as the clear hide.

One thing I never did like was the fact that if you have an arrow penetrate a deer but not make it out the far side ... if that arrow slides backward a few inches the blades start to close and you no longer have any cutting surface moving around inside the deer as at is running away. Just like the fact that mechaicals are so much safer than fixed doesn' t get mentioned often .. I think this point gets looked over frequently .. as I would imagine a fixed head, razor sharp blade bouncing around the body cavity of a deer would do FAR more damage than any mechanical that has closed as the arrow started to back out.
