No pattern yesterday, two of us on the boat fishing with totally different rigs, I was using lures (hokkais and muppets) with a small amount of bait whilst Tony tried flowing trace with crab and no lure. Results were we both caught almost at the same time .............. therefore leads to the thought that "anything" will catch if you hit the right spot at the right moment.
There was a difference in the way the hook was taken ..... the crab was greedily taken right down the mouth whilst the lures were top of mouth hooked.
