The problem is how do you define "needed" ?  I've seen the broken crankshafts, they do happen.  And although the breaks are sudden of course, I believe the damage happens over a long time, likely only when running at one particular (resonant) rpm.  If running a dampener (it's not really a balancer since the TRactor motor is already balanced without it) will lower the chances of a DNF and lost weekend from a broken crank, maybe it's worth sacrificing .01 second off your lap time.  (Or shaving that much more weight off the flywheel.)
