Hey Kunni, Only barbless on all my flies, but I have been starting to keep track of specific hooks and trying to see is there are any relationships between specific hooks an lost trout, big or small. Now that the fish are cooperating it is easier to notice trends regarding keeping them on.
I have two details that I am focusing on. Is the hook up to the task strength wise? I lost a fish a couple weeks ago that was one of the bigger I have had on, and lost him. Checked the fly and all looked okay and I chalked it up to lack of skill on my part but then I lost 3 more fish in a row, but nothing big. When I really checked the fly the gap looked okay but when I held the point and pulled down the gap opened far more easily than it should have.
Second detail is sharpness of point. I have taken to sharpening all my fly before it hits the water and after every hookup. I know this may cause it to rust sooner but that is not an issue as I am will just ty more. I think it has made a difference at least on my count but with fishing you never know.
Stay with the barbless, much better on the fish for release, and try a couple other brands of barbless. See if you notice a difference.
Hook stayed in fine for your big one this year, and the rod. Wouldn't beleive it if I didn't see it!!!!
