Question for you matchmen

Hi
In Bob Nudd's article in last weeks Angling Times, he is talking about
dropper shots. He fed some small balls of groudbait and was fishing 3 ins
over depth. Later in the session he started getting bites on the drop. My
question is what do you guys do ....
Do you start fishing at dead depth or even off bottom, or add more
groundbait to try to draw the fish back to the bottom.
Or do you continue to fish over depth and just try to hit the bites on the
drop.
