What is the difference between helical and offset

Both work equally well. Straight fletching will set all three vanes in a straight line down the arrow shaft. This style is popular for crossbows with narrow rails and archers using traditional equipment. Straight fletching offers the least amount of drag in flight, giving a very slight increase in arrow speed, at the loss of some accuracy and broadhead stabilization. High positioning accuracy and backlash stability. The hardened helical gearing ensures reliable backlash stability. Power density.

Pros: Maximum arrow stability best choice for shooting broadheads , highest accuracy at longer distances due to the arrow spin, least affected by wind.

Once again very similar to bullet rotation caused by the rifling of a gun barrel. Vane size length and surface area also plays a large role in the amount of stabilization your arrow will receive. Small low profile vanes will do less to stabilize the arrow than large high profile vanes. The more or less surface area a vane has, the more or less contact it will have with the air. Higher surface area vanes are more effective at correcting the arrow in flight. This plays a large role if you release an arrow with bad form because the fletching will help correct this to a slight degree shortly after the arrow leaves the bow.

Bow form is still critical, but this gives the archer a small amount of leeway. My friend Tim Ostlie prefers to use 2" high profile vanes with a slight offset to steer his large fixed blade broadheads. There are trade-offs you need to think about when selecting a vane. Higher profile vanes increase the stability of the arrow but will slow the arrow down. Vanes with greater surface area are heavier and slow the arrow down, but they are also better at correcting arrow flight.

Overall, choosing how to fletch your arrows and selecting the style of vanes has a lot to do with what you will be doing with them. Bowhunters should consider choosing a fletching setup that will produce higher accuracy rather than more speed because speed is hard to tame and is not that forgiving. Fixed blade broadheads are harder to stabilize in flight than mechanicals and field points. Large, high profile vanes will help stabilize the arrow in flight when using fixed blade broaheads, whereas with mechanical broadheads you can get by with smaller vanes.
