We're missing Triangle shots so I thought I'd post a couple. I originally bought it because my morning coffee routine was annoying other campers. Trangia burners are practically silent. I've since acquired a "full set" (second hand, good price) and was comparing boil times. Surprisingly, the triangle's only about 40 seconds slower than the 25 UL, not a meaningful difference on an 8-9 minute boil, and it packs down to the size of a postcard. Plus the burner of course, which lives in the mug along with fuel, coffee, milk and firesteel. It's a neat all-in-one set for a peaceful morning cuppa but too slow and "flamey" for side-of-the road breaks.
