RE: slick trick blood trails
Relating blood trails to broadheads is like saying tires suck because you hit black ice and crashed your car.
If the broadhead is sharp, stays together, and gets a passthrough, it has done it's job as well as any broadhead will. Every deer is different. I have had some that bled like there was a garden hose of blood flowing and others that showed little or no blood on good double lung shots.
Many times if you hit them just right, you can get fat that plugs the low exit wound and keeps the deer from leaving a good trail. They are bleeding out just as quickly, but it doesn't pour out onto the ground.
Change heads if you want to but beyond a certain point it is the specifics of the shot and the anatomy of the deer that determines the quantity of blood on the ground.
