I don't have a favorite brand of tubes. I match the thickness of the tube, along with how I rig it, to the conditions. I prefer an internal weight, be it jig or tube weight, mainly because they don't inhibit the tube's inherent action. That factor isn't important when dragging a tube or flipping, but I do both with internal weights. You can even rig a tube weedless on a jig head.
A tube's action occurs on the fall, so that (vertical) is the type of presentation I suggest you start with. Like most any soft plastics, they can be rigged and used differently in many situations. I'm not suggesting you only use them for a vertical one, just start there.
Use the lightest weight you feel comfortable with. More so than many soft plastics, you need to be a line watcher. Let it fall on slack line and count it down. Don't hesitate when setting the hook, the fish will swallow a tube quickly because it's compact and soft.
One last thing, Glenn has a video on here about tubes. It's well worth your time to find and watch it.
