I think maybe it is also some misconception as to what size trout should be.........
2lb is a big trout on a wild loch, 3-4lb is a monster!
But the rod you need to catch these trout on most wild lochs, needs to be a 6wt, 7wt, 8wt, and thats nothing to do with the size of the trout, its the weather that determines rod choice, and whether your in a boat or on the bank.
On a river it is similar, however when the weather is right catching a 1lb brownie on a 3wt rod it feels huge!, catch it on a 7wt and it feels small
.......
So what does this tell us.........it gives a perfect excuse to go and buy more rods!!
.......3wt, 5wt, 7wt......oh and varying lengths, so 8ft, 9ft, 10ft and maybe an 11ft.
There you go I've justified it, go get a another new rod.
