Here are a few ways I have used tubes FWIW ...
1 - Traditional ... with a tube head. Drag or hop on the bottom.
2 - Flippin ... Bullet weight, EWG or Flippin' hook. Hydrilla all day.
3 - Mojo Rig - A finesse carolina rig and a 3.5 finesse tube. Deadly!
4 - Shakey Head - Keep those tentacles dancing at the top. Megastrike tubes and their Shake E 2 jig are awesome for this.
5 - Drop shot - 2.5 inchers nose hooked. Not much success with this technique.
Never tried weightless.
