I'm not using one!

I usually copy something only in the moment and immediately "clear" my clipboard by CTRL + C'ing a single character from some textbox/selectable field :-)

For me, it's not a buffer but just a line of communication between two programs. When I have tried to treat it like the former I have found that mistakes are common and the benefits are very slight.

Might be worth it to automate the clearing after a paste event. If you want to paste multiple times then you'd need to give it some time, like 5 seconds after the last paste etc.
