hi mate,
i use the chod rig alot nowadays and has become a vital part of my fishing. however i do not genrally use it on leadcore the reasons being: 1) had no leadcore at the time
2)leadcore can arguabily be dangerouse
3)it sticks out like a saw thumb (in my opinion)
And the list goes on...
I now use amnesia as a leader instead of leadcore, this will make my rig less visable and give me an "edge" over the others
i attach the leader the same as you would leadcore (via loop) Although the rig does tend to be less notecable it can need aditional weight due to the lite amnesia leader insted of the heavy leadcore leader!
I hope this helps, feel free to ask me any futher questions
Tight lines.
