Talking about small flies, these are the 2 smallest that I use, and have caught trout on both of them.
A 2 pound tippet is too big to go through the eye, and I have to go down to a 1 pound tipped, with a long taper cut in the line to be able to thread it through the hook eye.
I don't have any, but I have seen flies well under half this size.
The last trout I caught, last winter, was a 3 pound rainbow at the Lower Illinois River, and it was caught with the top fly that is shown on my fingernail. With all of it's aerial acrobatics, and on 1 pound tippet, I was shocked I was able to get it in the net.
