RL LAWS FOR RU
THE 22M LINE
I would like to see RU do away with the current 22M line. Either push it out to 25m (a true quarter-line) or bring it back like RL to 20m (the "Gain-No Gain / Mark" provisions would move with it).
THE 40/20 KICK
I like this. It brings skilful tactical kicking into play, and has the potential to be a lot more exciting than the current "tactic" that seems to prevail in RU, i.e. belt the bloody pigs-bladder aimlessly into the air and hope the catcher makes a mistake). As a bonus, the 40/20 kick forces the defending player to play at the ball because he knows he will lose the throw to the line-out if he lets it go into touch.
RU LAWS FOR RL
THE SHOULDER CHARGE
I don't like it, and IMO RL should consider making it illegal. The potential for injury (from the full weight of a player at high speed using the point of his shoulder to strike an opponent) is too great to be ignored.
PENALTY TRY
The penalty try Law in RL is far too restrictive.
Section 6.3 (d) the Referee may award a penalty try if, in his opinion, a try would have been scored but for the unfair play of the defending team.
I like the RU Law better because the balance of probability favours the non-infringing side.
Penalty tries are very rare in RL. I can only ever recall seeing two;
► the NRL Grand Final in 1999 (for Melbourne against St George)
► the 2008 World Cup Final (for New Zealand against Australia)
I have seen a number of occasions in RL where a PT would likely have been awarded if they were using the RU criteria
