Do you make the double walled style of Pepsi Stove or the singled walled ones?
Mine are double walled with the bottom full height to keep fuel loss to a minimum.
I?ve played with both and the doubles are easier to fill and light.
Truth be told my last stove was a Coke, Sierra Mist, Red Bull combo. <img src="/images/graemlins/grin.gif" alt="" />
