Gah, I've been practicing all day and I can almost taste the 6K loop's sweet, sweet damage. I've been doing the 5K > 2S > 2D > RC > 6K > Break > 6K > Break > 2S > 6K > Heat Knuckle > Extend combo and can make it up to here: 5K > 2S > 2D > RC > 6K > Break > 6K > Break. I can't, however, connect the second break with the 2S. I'm assuming I'm just not quite fast enough, but I dunno. Anybody have any suggestions?
