OB Left, could you be straightening your back leg when you
go from the top to the end? Vasquez said in his book,
Try cupping the the wrist, but allow the the back knee
to straighten. You've lost your balance again. You still
can't break 80. Make no mistake, the back-knee position
made Ben Hogan's swing. (Hogan said so, I didn't).

Homer said in 7-16, "If the straightening Knee is allowed to
lock "beyond center" the subsequent unlocking is disruptive.

I assume that you are swinging. But being on Yoda Lukes
tread (Yoda Luke being a hitter), you would not want to
go from the top to the end as a hitter.

About Cupping, Vasquez said the Hogan told him that cupping
gave him balance. On the other hand, from talking with Yoda,
Yoda is not a fan of cupping at the top/end, because it sets
the foward hand in a bent condition, if held to impact it would be
the number one mistake of not having a flat forward wrist at
impact.
