Hi Matt
Well done on the bass, I am yet to target them of the Gold Coast here if you ever need to fill a spot on the boat let me no
I think the FCL jigs you are using without seeing them in person only a photo on the net might not be the jig you are after, a Jigging Master 500gram rocket jig should get you down faster as it is more tail weighted, the lumo ones are deadly in that depth.
I have some 2kg jigs coming from overseas at the start of next month, these will get straight to the bottom and believe me the bass will climb all over them, I got dusted will using one on my last trip in New Zealand
Cheers Andrew
