I tie mine like big bulls too. I had one fail earlier this year but it was my fault. I did not make the burn balls big enough. That is one of the most important steps IMO. A big group of us were sighting in our broadheads before a trip to Texas to hog hunt. It hurt some but looking back it was worth it...everyone got a good laugh and I learned to be extra careful when tieing them to make sure they dont fail anymore.
