Wherever this weekend is, if it stays, it HAS to be removed from the SuperLeague competition.
We have the only league that I know of where every team plays every other team twice (home & away), PLUS 1 additional game where some contenders (Wire/Leeds) get and easier game every year (Hudds/Bradford), whereas other contenders (Wigan/Saints) get to play each other. And then to cap it all, these results are used to decide the league.
Either kill it or (better) make it a pre-season knock-out competition (maybe 20 minutes each way) or even (as has been mentioned before) play an entire round of the CC there instead.
But for ****'s sake - DO NOT continue with it as a "normal" SuperLeague round.
