Like rock monkey says....rock monkey said:shoot whatever you like that works best for you.
depending on what type conditions you normally shoot it, you can change or stick with what you have now.
on my outdoor arrows, i shoot AAE SF23's low profile but still enuff to steer.
guys that shoot the long distance fita stuff like the low profile vanes.
on my indoor carbons, i have 3" duravanes and they work well. i havent shot them outside so i cannot comment on that aspect.
