I let the fish tell me what to do regarding the tail hook. Most of the time, with Bass and Walleye, I remove the tail hook. Most of the time when I fish for Trout, I leave the tail hook on.
If my hook-ups are on the front hook, then I will remove the tail hook so it is easier to remove the hooks. If I am getting a lot of tail tugging going on, then I install the tail hooks.
I had this issue last Saturday with large Browns and Rainbows using the Soft Sebile Magic Swimmer. Because it comes with only the one front weedless hook, I was getting tail tugged by about half the fish. I gave up some of the action and modified the bait with a single hook in the tail and the game was on.
Removing the tail hook increases the action. Adding or increasing the size of the tail hook reduces, or even kills the action, so, in general, removing the tail hook is a good thing while adding on depends on what the fish are telling me.
