I am shooting NAP RAZOR BAK 100gr broadheads.Does any body know if they are prone to wind planing down range.They penetrate great my wife only shoots 43# and gets full penetration.I hate to think we would have to switch.Thank you.

If your bow is properly tuned, they should fly great. There's only one way to know for certain.......

Before Nap took the razor bak over i used to shoot the razor bak 5`s and never had any problems with them.

they shoot fine, just tune your bow and use enough fletching to control the arrow.
