lol i have to admit we only fished in the morning and i got a fish within half an hour then went home 
I’ll fish a little longer next time, and incidently i did exactly the same rig as you, with a sinker up the line and livie on trace sticking out the bottom.
The fish often eat the bully whole so you often gut-hook them, which is fine if you plan to keep the fish but not if you plan to release.
What size hooks were you using I used small hooks, a single size 1 hook through the bottom jaw of bully.
