Has anyone had( or heard of) lack of blood trail or lost animals due to smaller wound channel.
A high shot on an animal with a smaller broadhead has given problems following blood trails--as the bleeding occurs internally.
However don't be mislead about the cutting diameter of the smaller broadheads--the entrance wound isn't very alarming--but I can tell you the 'exit' laceration is a different story--quite a nasty wound.
Nevertheless, the smaller heads do get the job done, the SteelHead expandables and the Slick Trick fixed blades are two of the smaller heads I've used, both of them with good success.
Put that arrow where's it's supposed to go and that animal will not go far from your stand.
