I usually use 120 grit regular sandpaper. I have never had a problem with the paper going down the hole. I make sure I have a bit of it extending above the hole so I can see what is going on (although if it tore half way down, I sure would not see that). If the pin was quite loose and other pins are fairly tight, I will use a full wrap of sandpaper and come out somewhere near the torque of the other pins. If the pin is loose and the others are kinda loose, I will use a partial wrap and come out good. That's the ticket - regulate end torque by considering the initial looseness and the target tightness and use an appropriate percentage of wrap. No guidelines for this though, just gotta experiment. A good feeling for it comes after only a few pins though.
