Pocket Rocket. It has a very intense flame and it funnels it right up into the "sweet spot" of the XTS. Brad, if you fold the PR pot supports inward to fit inside the ring, they actually will raise the pot slightly higher. It also decreases stability obviously, so their is no gain in doing that. In this photo, you can see the flame is totally utilized, nothing even showing coming outside of the convection fins, or up the sides. Walker6's similar photo shows a flame that is a little more spread, and perhaps a little farther from the bottom of the pot.
I think you've got the answer! Good stuff.
