Never cared for the four inch feathers. I am an oldtimer and my arrows have feathers that I burn into shape. They are 5 3/4 inch long, med/high profile, in shield, parabolic, and banana cut.
I love the look of a large feather in a quiver, just makes me think of compound bows, with overdraws when I seen a seven inch cap, with what passes for feathers now-a-days.
I guess I am a bit of a romantic when it comes to traditional bowhunting, and feathers. I know I don't need all that feather on my arrows. Heck they bare shaft out to thirty yards.
I know I could get a faster, and quieter arrow by going lower profile and changing shapes.
I am just in love with the look, that I copied from a set of old Ben Pearson and Fred Bear arrows I purchased in the 60's. They had those 5 1/2 high profile feathers, with that 11 1/4 inch cap, just beautiful....I guess if Tred can do it the Barta way, I can do it my way. You should do it your way too......
