RE: Speaking of physics - STS thought
Fran,
The point you are making is the same one that Len from Maryland made to me when I asked him what he thought of the STS on the Vectrix.He stated that you would need 2 spaced equally on the string to get the full benefit.
The Vectrix I shot did not seem to vibrate any less than the Trykon, Allegiance, or the 2 Matthews I shot.
