Ivan Marks for me! Once spent 1/2 hour talking to him on the end peg of the next match down from the match I was on, on the Trent. Didn't know who he was when I was talking to him. It was only after I found out who had been fishing that peg.
He never let on either, but what a stickfloat angler he was, catching ever other trot down his swim. What an informative, nice bloke to boot, in the short time I watched and talked to him. I probably learned more in that half an hour about sticking on the Trent, than I'd learned myself in the previous 5 years of fishing it.
Then there were other anglers in the club and went on the club matches, who no one knew at a national level, who had that type of magic like Ivan. Alan Grey, Ted his brother-in-law, John Mills, Cyril Austin, "Snelly" Harry Snellson. As a 16 year old kid you just knew you were there as pools fodder for these guys, but you kept going on the matches and paying your pools money in the hope you'd turn em' over. Never happened though!
However, you hoped that you'd get drawn in the pairs pools with one of them and they'd then share their magic with you to win the money. Happy days!
