I love feathers myself , switching this year from 4" to 5" madea HUGE diferance . For you guys and gals who like vanes as much as I like feathers , I guess this will be something to try , switching from 4" vanes to 5" i presume would have similar results at a lower cost . Now to the drawback , thy say your groups tend to open up farter down range with more drag at the rear of the arrow . I have not noticed this much myself as I genraly shoot only out to 40 yards , but this maybe something to consider .
