I have been bass fishing for nearly 30 years and up until this year I never had much luck with tubes. This year I got a pack of Vertical Lure Tube X Tubes in a give away. I texas rigged them on a 4/0 Trokar tube hook, 1/4oz Vikes tungsten weight  pegged with a 6th Sense Stopper, a Powell 775 flipping rod, Quantum EXO reel, 50lb PP, and absolutely had a blast catching fish on them all threw spring and early summer, pitching and flipping the outer weed edges in both ponds and my favorite lakes. However I did not have much luck with them once summer took full effect, much better luck with the Pit Boss and Rage Craws in the summer, but come spring 2016 you can bet the farm I will have a tube tied on again. 

I used tubes for LM two seasons ago, and was very successful, but I was using a specialized rig called the "Boob Tube", (developed by the Fish'N'Fool, I think). Except I used monster 6"-8" tubes by Mizmo and Basstrix. It worked really well, this time of year on suspended fish. I don't know why I never used it much after that, guess other techniques were just easier. It looks like this...

If you want to use an internal weight and tex pose the hook to fish in heavy cover, google the "Stupid Tube Rig".

Been useing it for years
