The one day that I did get to fish one of our single barbless rivers only using Kwickfish I ran the 4 bead chain set up off of the belly hook on a K-15. The one thing I did do that was different this time was to add a piece of backer rod where the hook attaches to the bead chain (about 1/2 inch pushed on), I went 4 for 4 on takedowns and solid hookups, put one hatchery silver in the boat, let on upclipped silver go, lost one king due to the Power Pro burying itself in the spool (newly spooled up and first fish of the day) and lost one king when my Bud knocked it off at the net . I am going to continue to try this on springers this season, it seemed to work out. I think that there may be nothing more frustrating then to see your rod tip just bury only to come up empty.
Good luck and tight lines, Jeff
