Personally, Im a tube case guy. They provide great protection, and are stronger against crushing type damage. That said, they are several times heavier than options such JBs interiors.
John Bartons Ultrapads are best in class in terms of protecting cues. They pretty much surround the cue in padding, and are very light compared to pvc tubes.
Im a big guy, and dont care about a couple extra pounds. If you are going to be carrying your case from the house to the car, car to the pool hall etc, most people dont complain about the weight of the tubes.
If you are playing tournaments where you are at a venue all day having to walk around a lot while carrying your case, the lighter weight options are a no brainer. :thumbup:
