Going back about ten years I was the only person useing a running lead system with a bottom bait on one of the lakes where I fish.
Then one day in a bankside discusion, one of the lads said; I like that rig that Baz uses.
Staight away I was the centre of attention, so I covered my rig with the palm of my hand and haunched my body over it like we used to do at school so nobody could copy you. I wanted to keep the rig secretive for a while longer. Everybody else was useing semi fixed pop up rigs.
Today, I would say that 70% of them are useing running leads with bottom baits.
