On Titanium vs HAA. Ti heats hot but also cools down faster. HAA usually heats more evenly and retains heat longer. This leads to less burning if one is actually cooking.

Ti is considerably thinner than most metals - though some HAA pots are catching up with wall thinness.

When I test stoves and pots, I do it with water just above freezing by a few temps (similar to stream water at altitude) and always test outside. If one wants to get really nerdy, use thermometers that are calibrated. Our weather here is excellent for testing as we have wind and often have temps of 40's to 60's - about what we see on trail outside of summer.
