LOL! That was a play at reminding you that sometimes people don't get acronyms, hyphenated versions of the original or short descriptions. It's often best to give more info to get more info... or at least have more people understand what you mean.
Anyway, IMO they are sort of a gimmick. While they may work every bit as advertised, hardly anyone is using them. Why? Because it's not necessary. They eliminate almost all standard rests and IMO are more susceptible to cross winds and hitting branches because they are larger and less forgiving. Can you picture them flying in the woods? I'd say sooner or later they will hit a branch throwing it off target.
This is an opinion as I have never used them and have no plans in the future. If you want to really check something out, check out
Blazer vanes! I have some buddies that are serious about their accuracy with broadheads and swear by them.
