the 2 biggest drawbacks I see to useing feathers are getting them wet and the noise. the amount of noise feathers make when shot from the faster shooting bows that we use today is signifigantly louder that that of a vane, not to mention how noisy they are if you bump them on something.Furthermore I have watched shooters all winter shoot 600 with 55x with plastic vanes and you dont need to be anywhere nearthat accurate to double lung a deer. If there was an advantage to the feathers then I would say go for it, but in my opinion the disadvantages out number the advantages by quite a large margin
