After 40+ years worth of broad-head killed critters I'm pleased to report very few lost animals and none that I can blame on the broadhead. One lost animal was due to a poor tracking decision I made. The couple others were because I missed my spot.
However, I've recovered some broadheads after the shot that didn't impress me. Others I've found too difficult for me to sharpen (all 3-blades).
There are several I have right now that I wouldn't hesitate to use interchangeably; Helix, Montec Carbons, Magnus Stinger, and some new Silver Flames. I lean heavily towards 2-blades, mostly because I've bought into the "less than 50# draw weight 2-blade recommendations".
I've killed critters with heads long ago that I would consider trash in these days of super broadheads: Green Wasp, Savora, and Satellites.
