Their for my wife. Her arrows are too stiff for fixed blades. I have used the Scorpions before and loved them, but these are way cheaper. I have a new pack of Rocket Steelheads, but they are not as sharp as the used Spitfire Maxx that I killed my buck with last year. Also I'm not buying her new arrows so I will be using mechanicals with a smaller cutting diameter. Not to offend anyone, but I don't need to here about Slick tricks, just Shockwaves.
