The above is an excellent post. I can't tell you how many times I have had a bullet that seemed to fly into the wind, only to see my flags switch almost immediately after the shot broke. I also can't tell you how many times I hear other competitors on the line when this happens to exclaim, that's impossible, goes against physics, IT HAD TO BE A BAD BULLET, A FLYER!! THIS AMMO HAS FLYERS IN IT! Of course, they are wrong. Need to pay attention to those tails! They drop before the flag moves in a switch, every time. If the tails are hanging straight down in calm conditions, look for them to start slowly moving into the flag stand. They will long before the flag moves and that little push can, often will, push the bullet the opposite direction of where your flags are pointed, or at least, change your hold point you were using for hits, into a hold that will score a 50 or a 9 (or a 10 instead of an X).

Edit: to answer the OP's question, I shoot Ray Hill Wicks style dual vanes with sail tails in dry conditions and Ezell's in wet conditions. Both with sail tails of various weights.
