They are lighter which means that the end of your shaft is lighter which means that they can do their job of stabilizing the shaft better and faster. Vanes can be up to 700% heavier which means that it requires up to 700% more effort from the vane to stabilize the arrow. What is easier to throw, a one pound ball or a 700 pound ball?

The are naturally textured so they "grab" more air which also leads to better stabilization.

They are more foregiving than a vane when making contact with an object. In other words they will fold out of the way where as a vane will bounce off an object.

They maintain their shape when traveling at high speeds where as a vane will flutter through the air thus loosing more of what little stabilization properties they had.

Feathers will still stabilize an arrow just fine if they get damaged. A vane will need to be replaced.

In my experience they are far more durable than vanes are. This includes practicing, and hunting.If you shoot through a feather they will naturally seaperate and stick right back together. If you shoot through a vane you got a big hole that is nonrepairable.

Feathers are not affected by temperature changes like vanes are.
