With the strong grip, the LW looks cupped when cocked. As a Swinger who uses the LW throw and a transition from cupped to arched, I couldn't care less whether it looks flat at the top. This transition from cupped to arched is effectively the LW bone outrunning the hands through Impact.
If, as customary, you chose to maintain the top of the Swing LW position to Impact, it's OK, because it IS flat, even though it may appear cupped with the strong grip. Just remember at Impact, the back of the Left Hand will be facing up out of the plane, rather than vertical to it as it would be with the neutral grip.
