Interesting comments all round - I agree with The Monk (Hi, how's it going?) that the 70s were indeed "secret squirrel" days. I started carping at the end of the 70s, just before the hair-rig...but at least people had something to be secret about then! Baits were individual then, and if you'd worked hard at developing a bait, baiting up, etc., then you'd got a right to keep quiet about it. As for rigs - well, those who had the hair first cleaned up.
Now, when any Herbert can walk into a tackle shop and come out with cutting-edge tackle plus bait and rigs in packets, all designed by anglers with more intelligence and imagination than them, there can hardly be any real secrets left - so you get these tackle-tart camo-clad "Action Man" clones who sit around, pose and look moody - they feel they HAVE to pretend to have secrets since they actually have NOTHING to be secretive about!
All they have is the latest tackle and clothing trends, but when it comes down to real angling ability and skill, the majority are "Instant Carp Anglers" who have not come up the hard way, through the various species and waters, learning watercraft and observation. They watch the videos, read the numerous carp comics, buy the right gear, rigs and bait, spod the required 10kg of pellets out - and then just sit there, 'cos they don't have a clue how to FISH!
