It is funny you should bring this subject up. I had a gentleman in the shop on Saturday who had some pretty wild suggestions regarding fletching styles. He claimed to have high speed photography/film footage that clearly demonstrated a high frequency signal emitted by vanes. This, in his opinion, was the reason that deer "jumped the string".

I had never heard of such a thing but did listen to what he had to say. Have any of you heard of something of this nature?

As for the laser issue, I think the laser centershot tool can be very useful on some bows but I have also found that it will not work on all of them. On some bows it can lead to very poor centershot placement. To assume that the laser is always correct sounds like somebody is just asking for trouble. Nothing with archery gear is absolute.
