All very valid points!
The rig is a float on the 20lb mono main line.
Sinker not sure the size it's 2cm diameter, under the sinker is a bead, then swivel.
40lb suffix leader about 50cm.
Either ganghooks or a circle hook.
4500 shimano baitrunner, medium-heavy daiwa sensor 12" (i think this may be a bit too heavy).
I'm pretty sure my casting action is too fast as well causing a lot of strain on the main line. The problem with casting a float is that it gets to how should I say it, terminal velocity then just stops dead at a certain distance. That causes me to try to cast harder and harder each time and then I end up breaking the main line Also line getting belted onto the rocks by waves is like a bad habit
Maybe a cigar shaped float might help hehe
