The question begs to be asked ... are you applying brakes (space bar) after touchdown ?
Typically, you can't get the gear down on most planes until you are under 200 mph. With that in mind, coming to a controlled stop, a speeds under 200 mph, by applying applying brakes, should stop you far before you roll/bounce off the runway.
The trickest of planes to stop, IMHO, is the F4U line of planes. These planes require a longer roll down the runway, prior to applying brakes. You must make sure that the tail wheel is on the ground before applying brakes. Once under 100 mph, the tail wheel is firmly on the ground, and at that point, you can stomp on the brakes without causing the plane to veer out of control to either the right or left.
