are the banana shaped feathers loud? love the look but don"t want to put the effort into them and find them to sound like flying tanks..

It is directly related to how high they are.

I don't think they are loud,I hear more noise from a high shield feather.I think the rounded profile helps eliminate some of the noise.I think the sharp edge of the tail will make some noise if it's a tall shield.I like banana cut feathers,I've bought them and I burnt them.

me thinks the degree of helical could be a factor.. I have not noticed noise with 5 1/2 inch 7/8 inch high bananas- but gotta wonder about the degree of helical--- ?????  :confused:  

its the little things that get ya.

the more helical the louder they are.  but they look great on wood shafts and really stabilize better with a large broadhead on the arrow

shoot often
