i am neither ultralight or heavy, but i do like to carry wine in a box (minus the box.) it's usually cheap and drinkable, but it takes up 3l or 5l of space and weighs a bit more than 3kg or 5kg initially. you can reuse the bladder as a water container. i also enjoy other beverages which often come in glass containers and are somewhat bulky and heavy.

all my toothbrushes have handles, and i have never drilled or cut anything to save weight. i rarely feel that i have suffered needlessly or failed to reach a destination due to excess weight, and it doesn't bother me much if i reach my destination a few minutes earlier or later. traveling isn't racing or training to me, although i will occasionally flog myself and hammer a big gear just for yucks.
