This thread had got me thinking about my gear. I am a backpacker and a bicycle tourist. I use a MSR ti kettle for backpacking and a GSI Soloist for touring. Phat and others talking about using a plastic cup made me think about things. I have been using a double walled ti cup. I don't like the single wall ti cups.

So, my plastic cup from the GSI Soloist will fit inside the MSR ti kettle and the cup has ounce markings so that makes it a double use item. The lid for the cup fits on the lid of the ti kettle and a large canister of fuel will fit on top of that and is contained with a mesh stuff sack. The weight of the kettle and cup is 6.6 ounces. Good enough for me. Thanks all.
