Gone But Not Forgotten
I've spent some time casting mini-flukes and roboworms with my heavier fly rods. Actually, "casting" is not the proper term - it's more of a lob, like nymph fishing in winter with a weighted fly, strike indicator, and half a box of split shot on your leader.
In this case, the weight of the "fly" so over-powers the line and leader, it turns itself over, and you don't need a tapered leader.
If I'm fishing in shallow water, I'll just use a straight 4-5 ft piece of 15# fluoro leader material; if deeper, I'll use 4 ft of 25# attached to 3-4 ft of 15#.
Not a pretty way to fish, but very effective for bass.
We used to do the same with nightcrawlers. It is terribly effective.
