Correct, and that should be it. The VR then goes back to the ptb, to see if there are any infringements leading up to, and the actual grounding of the ball,then make his decision.

That sums up my thinking completely. It’s the “shades of grey” decisions that are the most contentious and take the most time. I think a time limit should be in operation for those. If no decision is arrived at in say 40secs then go with the onfield ruling.

I see it a bit differently. If there were no video referee at the match, the on field referee would have to make a decision. So he is really saying to the video ref, ' If you weren't here I'd give a try / no try - unless you can see I would be clearly wrong...?'

I tend to agree; sending it up is a clear indication that he doesn't know - so why weight it with a decision that, by inference, is a guess? Just send it up and ask the VR to make a decision, without the daft caveat of finding incontrovertible proof that the referees guess is right or wrong?

I also think it should be used for foul play - watching a player continue to have an influence on a game only to be banned afterwards is galling in the extreme, and hands the benefit of the ban to teams who haven't been victims of said foul play; if the technology is there, why not use it?

Going slightly off on a tangent here, but does anyone else think that there should either be a VR at all games or none at all?

All games. In SL that is.

I’m not too fussed, but I just believe that it should be all SL games or no SL games. Not a VR at televised games only

Shouldn't go to NO VR at all. It'll only take a few occasions especially in a big game possibly the GF where a try is allowed when it shouldn't be and people would be crying foul that the sport took a backward step in getting rid of technology when nearly every other sport has embraced it now.

Would get rid of the on field decision or tweak it where if the footage is inconclusive then the VR can send it back down to the on field ref who can then signal and decide what he originally thought. The VR shouldn't haven't one armed tied behind his back like he does now.

My problem with the current system is that it's used too often. Does someone who watches all the sky games have a feel for what proportion of referee's decisions are overturned?
I would go with a captain's challenge (say 2 per game, lose one if you're wrong), but only when the referee is uncertain, as now.
So, if he awards the try directly, there is no challenge. If he goes to the screen with try/no try, it's effectively offering the choice to the captain. If he chooses not to challenge, it doesn't go to the screen and the referee's decision stands.
An example of this at the Wakefield - Salford game. Miller's try went to the screen as no try and it wasn't given. You saw miller shake his head when asked by the team, so he knew he hadn't scored. The no try wouldn't have been challenged and we would have saved a few wasted minutes.
