Hey all, I've got 2 shafts with Flu Flu fletching and g5 small game heads for squirrels this year.

I'm shooting 45# @ 28" with D97 string.

The fletching is four 4" untrimmed feather vanes and after some more research, it seems like these won't be good enough at slowing the arrow for what I want to do.

What type of Flu Flu generates the most drag? I'm going to be shooting up at treed squirrels and think that slowing after 20-30 yards is too far out. Is there a fletching that works better, say slowing the arrow at 10-15 yards?

I think I read that the spiral-type is best, but wanted to know if anyone had first-hand experience.
