I have to agree it all starts with a properly tuned bow. I shoot Slick Tricks and have for a few years now. They just spin test better for me than any other fixed blade. They are a 4 blade that flies just like a fp. The big move with fixed blades was the shorter ferrel, this shorter ferrel really helps stabilize the shaft during flight. The older fixed blades from years back were all longer and this caused more erratic flight.
