I've been away from this forum for quite a while and for my surprise I found out this thread is still "alive".
Like I said in a post before, the most sensible approach for an overspeed recovery on the A320 is... doing nothing! Simply sit and wait and monitor if the ATHR is doing its job. Don't touch the AP and most particularly don't use the freaking SB at very high levels.
KISS.
