I fished with one of the red bull lads in the Anglian water final last year. I got a fish and played it for over a minute. When I got it to the net i realised it had put my cast in a bit of a tangle.
As i sorted out the tangle (took less than 2 minutes) my partner had 3 fish in the boat in about three casts.

I never seen the likes in all my life. I was shocked.

Each fish took less than 7 seconds to get into the boat.
We were obviously over a pod of fish, but it was the way they were taking the flies on the roly poly. They literally just swam into the net after they were hooked. As if they were on a remote control.
My partner explained that they were swimming in the same direction as the flies and once hooked they just keep swimming in that direction. Its when they change direction and put on pressure that they take a bit longer to land
