Ive had great success on the T&W. Its a great way to fish from a yak because the troll is slower than most other methods. Its a good casual paddling speed (~2-3mph?). I think sandworms work best because they dont break easily. A night crawler would probably tear off the hook after a few minutes of trolling pressure. I've found that the T-Man tubes with a keel weight work best. Make sure you leave the natural curve in the tube as opposed to straightening it out.
