I was very skeptical about the TURBO's, performing like they say but after trying them I was truly suprised. I went from 3 1\2 - 4" groups down to 2" groups at 40 yards. The only problem I have found with them thus far is if your any kind of shooter you might break a few nocks and or arrows. Especilly with broadheads. I would not switch back for love nor money. Also it's so easy to refletch them so to speak it's not even close to vanes. Really all you do it pull one out and phus another in. Vanes, glue, nocks and time made my choice simple, once I tried them. Personall I use and love the DeadX, but the Hunter work equally well.
