RE: Vectrix or Vulcan
Were the bows IDENTICAL in draw length.(measured) Just because one says a bow is 28" doesn't mean it actually is 28".
This will have a dramatic affect on the feel of the draw cycle.
Another thing that will affect the feel is the way the cam is setup,meaning is the timing identical on both.If not,one will have a smoother transition that the other.Also,a HIGHER letoff will make a bow feel like it is much HARDER to breakover.
POUNDAGE is only ONE factor,there are many others.
