Hi Bill:

Being new on the forum I do not want to rock the boat, but with a shorter swung object the speed is greater when swinging such object.

Baseball bats are not 5 feet long.

Stiffness from cuting down can reduce swing speed and also the shorter arch of the swing.

A shorter iron for an example with a shorter swing may not recover as fast in the downswing and most would tell you to go to a more flexible shaft. Just the opposite of what should be done. Dynacraft Study.

Swing Arch is more of a concern for the upright type swinger in which the right shoulder is lifted in the back swing to allow the left shoulder to replace the right shoulder and the club remains in front of the body and there is more of a direct path to hit the ball.

Depth in the rounded swing provides a greater swing arch by swinging further around the body, the hands drop down from the hip action and then when there is connection you whip around.

You are correct, the player must be fitted for their swings and their results which does not always match what is on paper.

No pipe cutters on graphite shafts please.
