Swhacker Broadhead review

I have always shot fixed blades on all game until this year. I had a friend who convinced me to try the Swhacker on my general archery hunt here in utah.
I don't have a high end set up with any crazy speed here is what I am shooting.
2005 diamond victory 70 lbs draw 27.5 draw length 398 grain arrow weight. These heads shot amazing out of my bow and took no tuning. My Bow was well tuned when I began shooting them.
Long story short I took a Big Dry cow at 20 yards. Perfect broadside shot through shoulder bone. I got penetration up to my fletchings. As soon as the arrow hit I saw blood squirt so knew there would be a good trail.
Once I started tracking I was amazed at the blood trail. There was steady blood that had run or sprayed out of the elk the entire 50 yards she went. When she passed trees they were sprayed by blood. So far the broadhead had lived up to what it was supposed to do.
Then I got to the arrow and got to look at the head and blades. This is what was impressive to me. Everything was intact and 100% re-shootable. The blades were strait and sharp still. No chips or bends whatsoever.
Over all thoughts are this is a very well built head and lives up to what they advertise. It is very simple, tough, and efficient.
I appologize for not having pictures. I didn't even think of brining a camera on this General spike or cow hunt.
