I have not worked on these A/C for 2 years now, but from a MX point of view the extra cycles of operation of the spoilers does seem to cause excessive wear on the linkages between the jacks and the panel. They slam up and down.
I thought that if the switch was allowed to automatically go to the flight position on T.O. then one less cycle per flight would take place.
Also, if a restrictor was put in the hydraulic line then a more gentle operation could be achieved and the wear reduced.
Just my thoughts.
