MSR now makes a nifty little canister stand that pretty well solves the issue of topheavy stoves. The Pocket Rocket with a 2L pot may be a different story: you've only got 3 points of support, and I've read reviews that say they're thin enough that they will deform under a 2+ liter pot of water, leading to collapse. Cooking with a pot larger than 1 liter has me reaching for my Superfly stove and the above canister stand. The Superfly, for a couple extra ounces, has 4 beefy pot supports. It also has a wider flame spread, which I've found is a better solution than the "pinpoint" flame of the PR for wider pots.
