In talking with the people from ProMatch, I got the impression the soldering methods are very similar. The bars Fusion use look really nice, but I am not sure it would make a huge difference with no air flow. I would assume that some of the heat would dissipate.
Fusion states on their website quite clearly they are taking legal action against competitors that "copy" their technologies. I would think ProMatch would differ their soldering process slightly to avoid legal action.
