Well, the short of the long story is that I got let go from two different jobs and spent a lot of time unemployed and a lot of time driving to a well paying but distant job. A lot of OT too, but that's what kept us housed and fed. 2012 was pretty much a disaster (financially) for us.

Excellent question. I actually think I'll do an entire post on that at some point, after some testing.

There are some things I can say without testing though, and I'll go through them by category:

COMPACTNESS
The Caldera Cone is generally a taller cone and typically doesn't fit into the pot. I say typically because Trail Designs does have one Caldera Cone, the Sidewinder Caldera Cone for the Open Country 2 qt pot, that does fit in the pot. As far as I know, all other Caldera Cones have to be stored outside the pot, typically in some type of plastic container, which adds weight and bulk. Note that I am speaking here of the aluminum Caldera Cone, not the titanuim Ti-Tri cone, also from Trail Designs. The titanium cones are wonderful (I have one), but they're in a different price range. Right now, I'm just comparing aluminum to aluminum.


On the other hand, the Bobcat system fits right into the pot.


Likewise, if you look at the height of the two stoves, the Flat Cat stove has a lower profile, making it easier to store.

I'd say the Bobcat is superior here.

EASE OF USE
There's nothing difficult to use per se about the 12-10 stove that comes with the Caldera Cone, but I really do like the low, open design of the Flat Cat stove that is the primary stove used with the Bobcat system. If you saw my firesteel demonstation video in my review on my blog, I think you'll see why. It's easy to fuel, and easy to light. I'd say the Bobcat is superior here.

DURABILITY
The Flat Cat stove is stainless steel; the 12-10 is made from aluminum beverage cans. I'd say the Bobcat is superior here, but do note that I'm not calling the 12-10 flimsy. It's just hard to argue with stainless steel.

SIMMERING
Both stoves have effective simmer rings available. I did have some trouble in windy, freezing weather with the stove going out when using the simmer ring with the Flat Cat stove, but I haven't done similar testing on the 12-10 stove. At this point, I can't really say which will handle foul weather better. Testing required.

WEIGHT
The two windscreens appear similar in terms of weight from what I can tell, but recall that the weight of a Caldera Cone varies with the pot. Larger cones are required for larger pots; larger cones are heavier. I don't have a Caldera Cone for the Evernew 1300ml pot, so I can't do a direct comparison. The gauge of the aluminum of a Caldera Cone is clearly lighter though, so I suspect the Caldera Cone will be lighter for the same sized pot.

The 12-10 stove weighs roughly half the weight of the Flat Cat stove.

I can't make a complete assessment because of the above mentioned caveats, but I think it's safe to say that the Caldera Cone system will be lighter.

EFFICIENCY
This one I can't call just on gut instinct feelings; I have to do a "stove off" under identical conditions. I suspect both will do fairly well. I've taken both systems out in high altitude, windy, and relatively cold 32F/0C conditions, and both have done fine. I do note some increased fuel consumption, but that's fairly typical. I'd really like to have two identical pots in order to do the comparison, but Evernew 1300ml Ti pots aren't cheap. That'll have to wait awhile.

CONCLUSIONS
Which is the better system? I think it boils down (if you'll pardon the pun) to what matters to you. If durability, I think the Bobcat, particular the Flat Cat stove. If ease of use, then perhaps also the Bobcat. If lightweight, then the Caldera Cone. If compactness, then the Bobcat. I think the prices (again, I'm speaking of aluminum windscreens only here), are comparable, but maybe the Bobcat runs slightly more. I'd invite people to go to TrailDesigns.com and FlatCatGear.com if they're interested in pricing though rather than relying on my poor memory.

Efficiency comparisons remain to be done.

Hope that helps,
