Winni and Squam are like night and day, we dont catch yearling fish hardly at all.
I've been told, trebles and singles don't make much difference, but we can de-hhok a fiosh much faster in a single hook fly than a treble on a spoon.
I think barbless or pinched would be allot less evasive, without the barb you can de-hook them in a couple of seconds minimizing the time out of the water and less damage from the hook. And if far less make the biat as fishless man points out, it would have to improve everything, ha,ha.
