Both of these string are the same material, I pulled open both boxes myself and they both said "Excel".
Thats why I was hoping the brace height would make a difference, my one on the bow right now is not twisted, at all. The new one I bought today required several twists to achieve the same brace height, the POI difference is not big, but big enough so I know it can't be used reliably as a spare.
Should it be twisted a bit? I can readjust for a twist, but what difference does a twist make? Why is the point of a brace height?

*EDIT* By "spare", I mean a second string that can be replaced in the field without readjusting.
