Good catch of fish there
Getting back to what you are asking, whenever I have fished two rods for snapper, it's almost as if they know to latch onto the lighter outfit. I often bring a small rod that really is a bit of a joke if I am expecting to catch a decent snapper - its more what you would use for stealth fishing for bream in canals with 2KG leader. But guess which rod I get the most bites and fish for the table?? I can stop snapper up to around 50cm ( had one beside the boat at wello recently, but he spat the hook - but that's another story) After that I am in serious trouble only because of small line capacity.
Want a real buzz? Fish 2KG for snapper. Sure you get busted off frequently, but if you stay connected, the light line gets more hits that is for sure.
