Hi Guys,
I was away fishing for an hr yesterday on the local River Ayr right away up at the start of it where the streams are only 12 inch deep and 6 foot across. I managed to get two 8"-10" trout which were very easy to hook on a dry fly (small white 16) then returned BUT i was plagued by an army of 3"-4" trout which were just making a fool of me trying to hook these wee super fast buggers

Every cast they attacked my fly but couldn't hook them? I did get one though which was super exciting, a 100mph speedboat going through the water everywhere lol
My question is why do trout get easier to catch as they get older and bigger as it should be the other way around? easier when young and inexperienced!
Id rather fish for these wee missiles than large trout as to me its more fun
