I've got last year's (or two years' ago?) pot, too; it works great with my Svea stove (we won't discuss how long I've had that.) I use that setup for winter camping, sometimes.

Currently, my default stove is a Jetboil PCS - it's not the lightest, but it sure is convenient for my style of cooking. I'm hoping the Optimus, at lighter weight, might prove equally functional; if so, it may be the final piece of a lighter-weight option to my gear that will save about 3 pounds (a lighter pack, a lighter tent, short sleeping pad with an inflatable seat cushion/pad extender and no chair) - but the lighter stuff will have to function at least as well as the stuff it replaces. (And I'm not carrying that heavy a load now - about 17 pounds before food, fuel, water, or winter clothes; 27 pounds with 4 days' worth of that stuff.)
