I may be playing the devils advocate here because I have never had my hands on a clikstand. I really like the idea, looks to be an excellent system.
I think there are a few holes in this review. One being that the only "data" is the cost of a clikstand vs. a caldera cone. Other than that, it is just one man's opinions and untested theories. The thing is, that a comparison to the caldera cone system isn't really the point. Yes, it supports any pot you choose and that is a plus. But to say that it is a big plus in comparison to the caldera cone is just opinion. That totally depends on the style of hiker or trip. Many of us will only use one pot anyhow, so if you are only concerned with weight get something that is both lighter and cheaper. If you want to really cook, get something that is cheaper and can simmer. I'm not saying the clikstand isn't a good system, just IMO, it seems to fall a bit in no man's land.
The reason the system doesn't work well with narrow pots is because of the stove design. Look at the flame pattern of a trangia burner vs. a 10-12 burner. The 10-12 has a more centralized pattern that is much more efficient with narrow pots. The trangia (or copy) has a wider pattern that will work better to have even heat distribution on wider pots. Use your equipment as designed. I wouldn't throw a 4.0 liter pot on a jetboil because it isn't designed for that, neither would i put a tall, skinny pot over a trangia (or copy) type burner.
My other thought is that if you want to really "cook", then the titanium may not be worth the price as much. The T2 clikstand may be light, but the multiple pots necessary to really cook are not. For the price of a T2 clikstand, you could buy a trangia 27 that was recently reviewed by Hikin' Jim, and that includes the ability to simmer as well as two pots and a fry pan. Of course a trangia 27 is heavy, but IMO, if you are going to be willing to bring multiple pots, might as well go all out. I've never actually searched, but i'd bet that you'd have a hard time finding a wind protected simmering capable stove setup that includes 2 pots and a fry pan that weighs much less than a trangia.
I see the T2 clikstand as a possible alternative for someone who likes to really cook occasionally and usually just boils water, but only wants one stove. With a trangia burner and a simmer ring and an extra pot or two, you could really cook. Then use the evernew burner and a wide pot for when you just want to boil water. Then again, I'd think a mini trangia would serve the same purpose for about $40. And if you add the clikstand with a evernew 900 pot and evernew fry pan, or even an evernew pot/pan combo, you are heavier than the mini trangia. Not to mention you will have spent close to another $100 in cookware.
