I didn't read all the posts, so not sure if these were mentioned. They seem to be fairly unknown. But, after one trip as a test run, I am completely sold on the Steelforce Phatheads. We shot the 100 grain head, which has .080" thick blades (not a typo!), and a 1 1/4" cut, and unreal sharp out of the package. Our test trip was a hog hunt, and the penetration we got was great, and the blood trails amazing especially given the poor blood trails hogs normally leave. All four of us needed no tuning to get them to hit with our field points. They were not a sponsor for us...but I am doing my best to get them on board with us! I will post some pix of the holes from the trip later. This pic is from their website showing the head, without the bleeder (which wedid have in for our hunt).
