If you like feathers, stick with them. They have many more advantages than disadvantages. Vanes only have one great advantage: they're waterproof
Amen.
I shot vanes for a few years, then went to feathers exclusively for several years. Over the past couple of years I've been trying to give vanes a fair shake again, but I've become fed-up with them.
In my book vanes have 3 advantages, and none of them have to do with arrow flight.
1) Waterproof.
2) Cheap (unless you use Flex-Fletch)
3) Easier to fletch.
Feathers stabilize any arrow better/quicker, are much easier to tune with any rest IME (Contact with rest/cables, etc is much less critical, if at all) and will still shoot well if you take a chunk out of them (unlike vanes).
I understand why folks like vanes, but for me they are more trouble than they are worth.
