“I'm wondering if anyone has tried to compare these fuels in a Trangia type burner?”

If it’s like the sterno jellied alcohol, I’d stay away from it. It’s hard to light and keep going in the cold. Also liquid alcy is much lighter.

And my two trangia tips for the day:
1. If you ever use normal alcy, don’t snuff it out w/ the lid. That usually burns the o-ring.
2. There are much lighter alcy stoves out there.
