I have 2 Diff pairs in the same dielectric Material (ISO370HR). One is Uni 
Stripline, One is Dual Stripline. Aside from the potentially different 
core/Prepreg material, resin content, glass weave (etc), and they are the Same 
Copper Geometry (say 4 mil line/7 mil space) and have the same impedance, same 
DC resistance  will I be able to observe a difference in Insertion Loss, Return 
Loss, or Insertion Loss Deviation ?
