I agree. Using something as small as a tea light for a stove is on the extreme of ultra light and if conditions aren't right you could experience trouble. My last trip I used a pop can stove with very good results. But I had perfect conditions to use it in. I have now fitted a cone shaped windscreen, a base insulator and using two tent stakes to hold the pot at the right height from the flame, I now use my heavier Trangia. That's about as lightweight as I'm willing to go from now on.
