I do a couple of things to keep the soft plastic trailes from sliding. First, is the old stand by of placing a piece of used plastic worm on the shank. Second, take an old 1/4 inch wide rubber band, and cut a coupld of 1/4 inch long pieces. Then, with some Carlson Fishin' Glue, fasten the pieces to the top and bottom of the trailer where the hook will be run through.
Another trick is using a Ninja "keeper collar" jig head, with the larger Ninja Claw. Instead of placing the trailer on in the normal way of sticking the hook through, as with a pork frog, thread the Claw over the keeper shank. The larger size will still have an ample amount of legs sticking behind the skirt, plus it will give more flare to the skirt.
