I own a 1.5 L JetBoil.

To lighten it:
1. I removed both the wire handles and
2. used a Dremel tool W/disc to cut off the handle attatchment metal plate.
3. Also I cut the center out of the bottom plastic "Flux Ring" protector. (But you could just keep it whole & use it as a second plate, the lid being the 1st plate.)
