Right, basically this is what I do, most others will nearly all favour for a free running link ledger,
now to to me this is actually inferior and doesn't actually work in how one thinks it works,
My therory is that if you use a lead that is say any lighter than 1 1/2 oz as soon as any fish picks up the bait I can assure anyone that this lead will most definitely move, it won't just sit there on the river bed and allow line to pass through a run ring or swivel eye of the lead and register a bite on the rod tip without moving that lead,
I've deliberately tried and tested this tactic in marginal clears swims on many rivers where every fish watched taking the bait all moved the lead, the only time the lead will stay positioned on the river bed and not necessarily move is if one uses any leads above 1 1/2 oz.
If this has made sence so far one needs to then realise that if using lead of say 1/4 - 1/2 oz which is what I often use or considerably less it doesn't matter if you set the rig up as free running or actually fixed because the rig in effect will act exactly the same regardless, it's basically a micro bolt rig affect if ones wants to get technical, but what I do is use the lightest amount of split shot that I can get away with,
With this in mind all I do is just simply pinch about 3-4 AAA shot directly onto me mainline about 18" away from the hook, couldn't get any simpler as a very light rig,
I've personally never ever had any issues or problems with this basic rig and it's a rig that realy does work for me when a lot of other known tactics can often fail.
