BB9,

I have been getting excellent accuracy with both styles. At longer ranges (35 to 40 yards) I noticed that the feather fletched groups started to open up a tad compared to the vane equipped arrows..I suspected it was because of excessive drag. I refletched them w/ a slightly less agressive helical, and longer range groups tightened right up.

Personally I am a feather proponent, though I do shoot vanes in certain set-ups. In this particular case I was initially concerned about spine being too weak w/ feathers, but that turned out to be no concern at all.

Oh..I'm shooting 100 grain points.
