I've done an in depth study and this is what I found out. If my shot placement is correct and where it should be all the broadheads work just fine. When my shot placement isn't good the reults vary widely depending on how bad the shot placement was.

with good shot placement all broadheads leave a good blood trail when the shot placement isn't so good the blood trails are not good either.

It's up to you to get good shot placement so the broadhead can work.
