I can't imagine I was the only person who was slightly sceptical about exactly how well having two whistlers on the same field at the same time would work.
But a fortnight in, it is difficult to argue it has been anything other than a success.
For anyone who doesn't enjoy the dubious benefits of a satellite subscription, this is how is works.
One referee takes up the usual position, normally in the defensive line, and officiates in the traditional manner.
The second referee stands in backplay behind the attacking team, keeping an eye on the play the ball.
The two swap roles, depending on who has the ball and how experienced each official is, throughout the course of the game.
It doesn't stop the men in the middle screwing up from time to time, but it does go a long way towards keeping teams honest around the play the ball.
The upshot is a noticeably quicker game, with plenty of end to end football. It's not quite traditional rugby league, but it is great to watch.
And I suspect it is only a matter of time - and perhaps training enough referees to the right standard - before we see it in Super League.

WHILE I'm talking about referees, Sky really need to sort out their camera angles.
The whole point of having a video referee is so he can make an objective decision based on conclusive evidence.
Not so that he can have a guess based on no more information than that available to the on-field official.
I'm thinking specifically of what would have been a fine try for Halifax's Lee Paterson against Widnes last week.
Robert Hicks referred the decision 'upstairs' to find out whether Paterson and his fellow kick chaser Shad Royston was offside.
The trouble was, you couldn't tell from the replay, leaving the man in the hotseat to take a stab in the dark.
Hicks might as well have given - or not given - the try in the usual way.
In the old days, Sky used to do things properly, bringing the giant cherrypicker crane with them to make sure they had a comprehensive overhead view.
With the building industry languishing in the doldrums, I reckon there will never be a better time to pick up another one on the cheap...

IT'S difficult to imagine what the players and officials of Wakefield Trinity are going through at the moment.
After losing Adam Watene last autumn, they now have to deal with the death of young Leon Walker, who collapsed after a tackle during Sunday's Academy clash against Celtic Crusaders.
Walker's death is a reminder of the risks players take when they run on to the field each weekend in order to provide our entertainment.
Trinity will now turn their attention to tomorrow night's clash with St Helens and crafting a fitting on-field tribute. The emotions will be running high at Belle Vue and no one should bet against them doing the job.
