Just my point of view would be freathers for a longbow, a recurve or a primative. Vanes for compounds and crossbows. A more intersing quiestion would be what type of cut and style of fletching to use: shield, parabolic -- yada, yada.
I have always shot 4" feathers with either a left helical or offset but put together a dozen eastons with AAE Max Hunters for out west this fall. Last years trip it rained atleast part of the day for 9 days straight! That can be alittle hard on feathers.
I have always shoot 4 of 5 in feathers with a right helical and they fly awesome, two things i really like about them one is they are very forgiving and will take a beating, and the second one is that they hold alot of evidence after u shoot a deer and what i mean by that is, the blood or the guts wont come off really easy and they also hold the smell if u think u hit it alittle back
