Hi mate, yes you are right regarding weight and size. Most surface stick baits are quite large when pushing the 40-60g mark.
I find getting fish to take surface lures hard in the harbour, i tend to use them at first light or when there are visible bust ups.
Tailor will take just bout anything that moves, kings and salmon we normally get on jigs such as the Palms Slow Blat etc.
in terms of poppers i love the Maria Pop Queen, not a traditional popper as it combines popping and a swimming action. Attached is a pic of a tailor taking the F130 40gram, although it was around the 40-45cm mark.
