You won't find a better broadhead, and I don't plan on switching anytime soon. They are very easy to sharpen, are wicked sharp out of the package, and hold an edge like crazy. They penetrate like mad and are very tough.
Don't believe me?
I shot a doe this season with the SilverFlame head. I was about 12 feet up in a stand when a doe came in at 10 yards, very slightly quartering to me. As I drew she looked up at me, and when I released, she jumped the string. My arrow went where I was looking, but the doe was a few feet lower. When she hit the ground immediately I knew I'd hit spine, so I quickly grabbed another arrow (Eclipse broadhead on that one) and double-lunged the downed deer, finishing her off quick. I pulled the broadhead out of the spine, noting that the broadhead had completely cleared the spine, going a few inches through the off side of the vertebrae, and coming pretty close to exiting the offside skin.
The next morning, when I went to clean the arrow off and sharpen up the broadhead, out of curiosity, I tested the edge on my arm. IT STILL POPPED HAIR OFF MY ARM WITH LITTLE TO NO PRESSURE! I was shocked! This is incredible performance.
We were able to examine the wound channel the broadhead made. Upon entry, the Silver Flame severed a rib at an angle. Continuing on, it dead-centered a vertebrae. After completely severing it, the broadhead continued another few inches and stopped there. I was EXTREMELY pleased and impressed by this performance!
The bow I was using was a DAS set at 52#@30", my draw length, with arrows weighing only 435 grains total.
