Used one (well the model without the non-stick coating) for years, and there's really not a lot that's a lot lighter other than a heiny pot. You can spend a fortune on titanium and not be any lighter either.

I am thinking outloud that if you are doing pct, you can alwaysdrink another big beer at a resupply point if your can gets too bent up.

If I were trying to go lighter, I'd use a canpot. as it is its plenty durable and has been all over the earth with me (quite literaly):
