Tubes and shanks aren't really my cup of tea, so I can't tell you much about trailing hooks. My trout flies range from sculpin imitations tied on size 3 AJ's at the big end to size 12 soft hackles at the small. (Every so often, I'll pick up a trout on a bigger streamer when I'm bass fishing.) I would probably tie and fish 14's and/or 16's, but I'm getting to that age where threading those suckers on tippets is frustrating without magnifiers or bi-focals, and I'm still in too much denial about lost youth to buy those.
