I owned a Katana 135, a Crossfire2 119 and jump now a Katana 120. Wingload 2 to 1 with the 120.
My experience: The flarepower of the Katana is a little better then the Crossfire2. In zero wind conditions I can walk/run out the Katana easily, the Crossfire2 mades me run faster.
The Katana is also a hotter canopy, more dive, longer recovery arc. Openings of the Crossfire2 are absolutly best in class, but I like the Katana 120 openings also. The Katana 135 opens more off-heading on me and I had a reserve ride with the 135. I don't know why, but the Katana 120 opens really better then the 135. They have different sliders, so apparently that is for a reason, but did not solve the "problem" entirely.
