If low point is always opposite the left shoulder and I positioned my ball opposite this point, does my impact fix position have my left wrist FLV or FUV? If the former wouldn't I still be able to take turf because my primary lever hasn't reached full extension?

Regardless of low point, you have to understand that you MUST NOT be uncocked at impact, because you cannot properly compress a golf ball unless there is uncocking from impact to separation.
