An intertesting thing happened at Marion last year that goes some way to solving this riddle. All my sticks were rigged with trebles, this drew some flack from the deckies who have much belief in singles. So one day I decided to rig with singles and give it a go. There was a period that day when I had four solid strikes in a row from big fish, none of which hooked up, I was muttering about singles and Scott the deckie was also losing his confidence in them. The next day I'm back on trebles and exactly the same thing happens, four fish lost on trebles with all and sundry asking questions!!
What does it all mean?
Some fish will get away no matter how you're rigged, sometimes in multiple numbers, this is just how it is. Wouldn't it get boring if all fish where landed?
Do what you do with confidence, as a firm belief that what you are doing will work, is probably the number one thing that separates the wheat from the chaff.
