RE: Does your arrow spin in flight?
Straight - Offset - Helical?

Another factor that determines the effectiveness of your fletching is the TURN of the fletch. If your fletching is arranged in a helical (spiral) pattern - like a boat propeller - your arrow will rotate in flight. Much like a football that's thrown with a perfect spiral, an arrow will fly straighter and be more stable if it rotates in-flight. Aerodynamically, a helical configuration is clearly a better choice. However, a helical fletch may not always be appropriate or necessary for your particular bow setup. For example, some arrow rests will not provide enough clearance to allow a helical fletch to pass thru without contact. In this case, many archers use an offset fletch, where the vanes are still straight, rather than in a spiral pattern, but they are slightly turned on the shaft to promote some rotation in-flight without compromising fletching clearance. For very unforgiving arrow rests with limited clearance, or for competition target setups that don't require much stabilization, the straight fletch may be the best option. Take a look at the diagrams below and the corresponding pro's and con's associated with each fletching configuration. When you order your arrows, you'll need to select one of these options.
