A big reason that the forces at TDC are so great is not due to
speed.  Piston speed by itself doesn't matter much except as
a determining factor in friction.  The big deal is acceleration and
that is at its worst at TDC.  One of the reasons long rods are
a good deal is the more favorable piston dwell at TDC achieved
with a gentler "jerk" at direction change.
