[pianotech] hitch pin hole

Greetings, 


Three years ago, I had a hitch pin begin to give way in the plate of a rather expen$ive grand. It seems that there was a pocket of something other than cast iron at the particular spot (Eb55).   It was under warranty.  Factory recommendation was to install a larger pin, which I did while accompanied by the dealer's technician.  Now, I get a call that the note is once again totally whacked out and I fear that the pin is once again beginning to lean into the string's pull.  I think the ultimate solution would be to drill a new hole perhaps an inch farther distally and just avoid the area.  Anybody else deal with something like this?  First time in 35 years I have encountered the situation.  
Thanks,
