feathers is all I use on my arrows and have only used them for over 20 years. In my opinion, they will stand up as good as the veins, but when they get wet, they do not look as good, but still shoot like they would when dry. I have had my arrows soaked so bad that they feathers look ruined, but after they dried, they came back to normal. Feathers is also lighter then veins (veins average about 3x more then feathers).

Feathers do have a higher drag when flying through the air. This will slow the arrow down faster, but since the arrow was lighter to begin with (with featherrs), it starts out faster. Also the drag of the feathers, will help with the accuracy, making the arrow more foregiving, allowing you a little more leaway in your hunting head selection.
