Hey beanz, it does seem to contradict itself. I understand what you are saying about a bolt set-up. What bothers me is, the following, when casting, what is the chance that the line might get stuck when hitting the bottom and the pop up might not be coming up at all, although drifting, but staying where it is, when releasing line.
When I take into consideration what gidneyboy said and a bolt rig system is used the lead will take it down to 6m and will not come up even when releasing line for it to do so or I am I wrong in this regard.
I tried casting with a long length, sometimes I get it right and sometimes not. In short I battle to get it right when using such a long hook link.
When I use a choddi I use a ringed swivel hook link, hook the lead at the end of the runner (20lb fluro) with a quick clip and put on the bead. For me I know what will happen when the lead hits the water, the hook link will slide as the lead is falling quicker than the pop-up can follow as it is behind the lead and will be stopped by the bead.
Then I ask myself again if a choddi oor a Zig is really that effective compared to other rigs for a person to go to all this trouble.
This is the reason that I am on this site, as I do need your guys advice to be one in front of my counterparts.
