Slime tube sealant, has anyone tried tube sealant on small inner tubes?

Thicker tyres! I'm telling you. Why are we injecting gunk into our tubes which ultimately increase weight and unbalance the roll when we could just get a slightly heavier but tougher tyre. Seems daft.

A dose of Stans in an inner tube weighs about 20g. IME, a tougher tyre will have a much greater weight penalty. I can't say I've ever noticed any wheel imbalance as a result of using Stans either in inner tubes or tubeless set-ups.
