Mick,
Even though they have mainly been big eyes and small Gee's up to 6-7kg, I haven't had any problems catching them at night on poppers & fizzers that had no glow at all.
They just 'found' the lure by its commotion.
Found the same speed retrieve worked day or night. A few more crazy missed slashes would happne during the retrieve that would drive them more insane for the lure.
Aaron.
