I just do not believe that for one second. The ronnie/spinner is imo right up there as one of the most effective rigs of all time. It's deadly. I've caught LOADS of carp on it.
Imo you can see very clearly in the Korda vids why they spook and that is because they know something is different, simple as that. It could be the way the hookbait behaves or it could be that they can see some part of the rig (they're not smart enough to know what a hook or a lead is but they can tell something is different). But they are just too inquisitive to ignore it imo. As long as the rig resets and there is food about they will normally take it eventually imo.
It's like when we fish on the surface. Unless you have them troughing like pigs you see them clock the hookbait all the time. They look at it, back off, come back, look at it, back off..... then on the fourth or fifth lap they take it. They just can't help it.
Totally agree. Creating that feeding situation is 100 times more important that than the hookbait or the rig imo. If you have any half decent rig that can reset itself, with any half decent hookbait on, it'll work if you can create that feeding situation.
