There’s a lot to go at here Chris but the gist of it is a simple confidence thing. That’s all.
im not saying your rig doesn’t work I’m saying it’s over engineered for what it’s got to do.
It’s a lovely carp rig. Very neat, very fancy but mostly unnecessary if used to catch barbel.
you cannot compare carp and barbel fishing to be anything alike. Or the species themselves to be anything alike.
Carp are often stocked in hole in the floor. They get leads chucked at their faces all day every day so they wise up and tricky complicated rigs with perfectly balanced bait presentation is often the only way to tempt those clued up fish to touch a bait.
now I love barbel more than any other fish that swims and I’ve targeted them for well over 25 years (only 38) but no point sugar coating the fact that they aren’t the most clued up fish that swims. In fact far from it.
For a start their favorite time to feed is either in a flood or under the stars and in either case your fancy rig goes completely unnoticed as other senses take over.
it would be lovely if a change of rig could be the difference between a blank and a right result but the reality is a change of location or general feeding and fishing tactics are far more likely to make that happen.
going back to the confidence thing. That’s important and if such a rig fills an angler with confidence then yes he should stick with it because if your not second guessing what’s out there, your likely to leave it out there.
my rig is a single length of coated braid stripped back a couple inches and a knotless knot. It’s caught a lot of barbel. When I blank The rig is last thing I think of blaming.
It’s more likely that this dumbass went and parked his arse in the wrong spot
