Well, I put the A111 and A110 up on the oscilloscope at high freq.  
In shape they're very much alike (slightly rounded leading edge, nice 
sharp trailing edge).  I couldn't tell the diff if I someone had a 
gun pointed at my head :-)  It seems that the voltage output of the 
A111 is slightly less than the A110 as the only difference, but that 
could be the calibration of my scope (very old).  Still remains a 
mystery I guess :-)
