The GF is the major prize for all SL sides at the seasons outset without a doubt and after that anything else is a bonus
The Challenge Cup is the next best prize on offer Kudos wise and it does carry a hefty prize fund for the winners
But IMO the CC doesn't get any clubs juices flowing until they actually reach the semi final stage,Some SL clubs are happy to be eliminated in the earlier rounds to concentrate on the SL competition safe in the knowledge that they could still get eliminated in later rounds of the CC
Out of the 3 competitions available to SL sides then I would choose
1: A Grand Final win without a doubt every time
2: A Challenge cup final win
3: A league leaders shield trophy
This trophy only becomes worthwhile nowadays IMO is when it is backed up by a GF win
If it isnt then it is merely a trophy that no one will ever recall who actually won it in years to come unfortunately
