> I like thick bottom disk pots for gas.

Are there any situation where thick bottoms are not best? Even if it is a responsive flame, you are still drawing a lot of energy out of the pot when you add food. It is good to have a lot of potential energy. On top of that, the thin ones warp so easily. and cooking on warped pans are so annoying.
