I have shot only three blade rocket heads the last couple years but I have just purchased the Slick Trick 100's and they fly unbelievable!! I Have already messed up 3 different arrows that I have shafted. 1 at 30 yards and 2 at 20 yards!!! I will definately shoot these from now on. They shoot as good as the 3 blade rockets and they have 4 blades!! Great for blood trailing!
