Good info Wheezy ... I do it the same way you do ..
Another thing I do .. when I first get a new Dansco .. before putting in all the plastic sleeves I vacuum all the holes for dust. I think when they cut the holes during manufacture there is a paper dust left. I have seen it get on proof coins (Lincoln cents) and over time start spots. Sometimes if I know I am going to be adding coins in the coming day or weeks I will not push the top slide all the way back in .. I will leave about a 1/4 inch so I can grab it better when adding those last few coins for that section.
