Only when all the slack is taken up. I fish my indicators at maximum drop, or resting on the ground.
I use running rigs over groundbait (which I think is creating the same effect as particles), where the carp are just hoovering up the whole lot as they "graze" along the lakebed, and where I am fishing with scattered baits, stringers and bags and have not noticed any problems.
In respect to when all the slack is taken up surely then slack lines would give worse indication?
If a fish picks up you're bait and pulls 2 inches of line through your leads run rig does your alarm beep and your bobbin move?
I believe it does, which is resistance, causing the bolt effect.
Imagine a slack line running through a tube, you can pull it quite easily, the water acts in this way, as a tube, so there is minimal resistance. The indicator lifts up easily with the slack line. I think the only resistance is when the slack line has been taken up and is now pulling tight
Now try a tight line cutting through the water, whichever way it moves there is resistance.
I see what you mean Nick. Next time I'm on the bank I'll give it a go.
