I use them both. I use all kinds of vanes...Blazers, Fusions, QuikSpins to steer my Abowyers or Snuffers. I hunt in a lot of places where I can't pick the weather I hunt in and it is tough to dry my feathers out in a tiny tent in Alaska.
If you look closely at the shafts in my quiver with this bear, you can see a mix of feathers and vanes. I shot and killed this bear with a feathered shaft about a half hour after a soaking rain. A few more minutes of rain and the feathers would have been soaked enough for me to switch out to one of the vaned shafts.
They both shoot well off an elevated rest.
