Tubes work there is no doubt. But I have to say I have had just as good a luck with plugs and 9er's and better luck with slinging eels.
The worm thing to me is still a mystery. I believe it was invented buy a tackle shop owner to sell more worms. Putting a dinky sand worm on 3' tube seems silly but I have done it and found little difference with or without. They don't stay on long. I can troll pretty slow in my boat...how slow is slow? Also I don't like how most tubes are made. They have a crappy single little hookin the back of the rig. I have had hits that take pull the tube nearly off the back of the hook.....
I plan on chartering a boat here with a guy who that is all he does and I will find out what the secrets are.
That said i rarely fish bass during the day anyway...I like the might bite.
