Just a little update. I believe I figured out my problem. Had a little "lightbulb came on" moment the other weekend trying out tight line nymphing and for the first time veing fairly successful. I believe my tenkara hookup woes have been that I wasn't keeping the line tight enough. Too much slack and I wasn't fully detecting any of the strikes. Will have to take my tenkara rod out again to confirm but I think I figured it out now.
