I am not physics professor here but.... If the fletching is offset like that then the foward most fletch will have less control over the arrow than the middle fletch which will have less control over the arrow than the rear most fletch. If all three were fletched at the rear most position this would yield the most control over the arrow. You can't make a 2" fletch into a 4" fletch.

I think that is just a new fad with people that are self proclaimed experts.

TFOX, I agree with you on many many things but serously, they look cool????? Those things look retarded.
