You are absolutely right about the angling Press' preoccupation with match fishing techniques and flies, Ron. The word 'match' might not be mentioned but the 'how to do its' feature match anglers, International rules sized flies and techniques allowed in match fishing.
That said, the anglers themselves are more than capable of catching big trout, and people like Ian Barr and Ed Foster often do, by design, using Minkies and other fry imitations.
Those big fish really are the Holy Grail of the big reservoirs. I remember being on Rutland with my late friend Luke Felton in an October wind doing our damndest to catch big rainbows and browns. They were herding fry shoals to the surface in open water, then attacking them. From above, gulls dived into the glittering, jumping scattering mass, snatching fry from under the trouts' noses. It was like a scene from a David Attenborough documentary, shot in the open ocean.
We were not expert enough and although I had one fish tear off with my tube fly, he came away. It still goes down as one of the most exciting day's trout fishing I have ever had; you could clearly see ten-pounders smashing into the roach fry.
