Yeah you are absolutely right. Pencil trick just makes things worse. Even with 850mhz and voltage=1 now I get a lot of HW errors. Time to break out the eraser!
Edit: Erased and back to normal. Zero HW errors @ 850mhz. Damn - now to find someone who can solder a bridge that tiny.
It was really annoying to do. What I did was get a gob onto the general bridge area, and then ran the solder tip (I have a fairly fine tip) along both sides of the bridge to collect any stray solder.
EDIT: Going to try using this to solder the bridge:
