I love them too. I went with the Ashby advice and went big FOC and the Grizzly's at the same time. I get NO windplaning at all--they shoot like field points. All my arrow-flight problems went away when I went heavy up front and carbon shafts. I file the angle of the blades down a little and sharpen them like a knife, no big deal.
I killed two elk with them. The first was a close quartering-toward-me shot. The arrow hit right behind the front shoulder and passed diagonally through and out and hit the far rear leg. The elk was dead in 10 minutes. The broadhead was still sharp. The second elk jumped the string and the arrow hit high in the ham. I never found the arrow. That elk, bleeding internally, went 80 yds.
And lets just say that I had to do some pest control with my bow on some pretty solid critters and was amazed how the arrows sailed through the animals. Everything died quickly. I bring that up because I have to be honest and say that these broadheads were not shaving-sharp, just goodnsharp, but they work.
