DS confidence checks

Just got back from running a DS demo (every Monday, alternating DS 
with FT), and I tried out a variation on the morale rules.  Instead of 
taking one check, and only the most harsh, when fired on, I made them 
take all aplicable.  So when the green-three scout platoon lost 3 out 
of 6 vehicles including the PL's vehicle, they took a total of four 
confidence checks.  And unsurprisingly routed off the board, rather 
than (at worst) simply becoming shaken.  I was very happy with the 
overall results throughout the game--morale became very real 
consideration rather than minor sideshow.  Comments?
