I think the whole issue sometimes gets a bit over-egged. Full-backs, or anyone else making a last ditch attempt to stop a try behind the goal-line are going to have to slide in low, which will run a risk of bringing knees and feet into play.
For ones like the Tomkins one versus Wire, he got a bit over-enthusiastic and it was a bit dangerous. I didn't think he played for anything but the ball. It would be a good time to use the 8-point try, but no need to get carried away IMO.
