2 advantages are 1) better accuracy and 2) larger wound channel.

Twothings cause the mechanicals not to produce the results people dream of.1) poor shot placement which can happen with any broadheadand 2) inadequate KE to push the larger diameter cutting surface through thedeer.

Please note: Taking short cuts is not and never has been my style. You don't need to be concerned if my bow isin tune or not. I have that covered very well thank you.

Your statement above is as ignorant as me telling you that you use standard broadheads to make up for your poor shot placement and lack of practice. Another ignorant idea is to think that there is only 1 best size/diameter broadhead. Each person has to match their equipment to there cutting diameter; just like matching arrow spine witharrow length and draw weight. You can't say that a 1 inch cutting diameter in a bow of 55 ft pounds of KE is the perfect choice for a bow with 74 or even 91 ft pounds of KE. That's why earlier I stated KE plays a role in using mechanical broadheads.

I currently have 74 ft pounds of KE on my bow and it is practically at "idle" right now at 62 pounds draw weight. When I crank my bow up to 70-72 pounds draw weight, I will be at 91 ft pounds of KE.I'm not going to waste all that good, hard to find KE on a 7/8 or 1 inch hole/wound channel. What good is it to have my arrow stick 2 feet in the dirt after a complete pass through? I choose to take all that energy and have it transfered as much as possible into the animal and still be able to reach both lungs. This energy transfer can only happen with a larger wound channel and that can only be given with a larger cutting surface that my mechanical broadheads offer.

Your foolish guessat how an arrow may have traveled through the pictures posted above will never convince me to use astandard broadhead with a smaller cutting diameter. I don't really understand why you are complaining about the dead deer in the photo anyway. The deer was shot, recovered and is hanging dead as dead can be. That's the entire goal, so no matter what path you think the mechanical traveled...the deer is still dead and that broadhead did it's job very well, even with an improperly placed shot. Keep trying harder, you have allot more work to do to change my mind.
