I used a GVP cone set up as my go to stove for 5 years — I wore out a couple cans from use — over time the flexing of the can caused pin holes in the manufactured creases. Not a defect, just a lot of use. This is a boil only set up (IMO). I’m surprised that you didn’t just buy the whole kit and use Esbit, it’s the lightest way to go, and you seemed focused on SUL. If you are just boiling water and doing freezer bag cooking, then no sponge needed for cleaning.
Since I mostly do freezer bag cooking, the Sea to Summit Long Alpha spoon is perfect, but it won’t fit into the pot.
Lastly, with a Caldera Cone, you have to have the pot the correct height above the stove… each Cone’s height is calculated to match the pot and the stove. The GVP is not designed to work with an alcohol stove, however I’ve used a 12-10 stove with mine, but it isn’t quite as efficient as other Caldera set ups.
For carrying stove fuel, I’ve found re-purposed water bottles work, but make sure you label them! I find that most of the smaller bottles with flip caps sold for these kind of stoves leak at the cap. I now use re-purposed prescription mouthwash bottles (not the lightest option) and they are nearly bullet proof.
Almost two years ago I switched to a Ti-Tri Fissure as my planned go-to stove system, using alcohol most of the time. As it turned out, I am again using my Svea 123 most of the time.
Here are my current thoughts on stoves. I don’t tinker with stoves much. I just use them for camping and backpacking.

BTW, I’ve been using Caldera Cones for around 10 years, so I have a lot of field experience with them and have high regard for the product and people over at Trail Designs.
