I have read a comment saying that the Katana is a completely different canopy than the Stiletto. It is, but I switched from a Stilleto 107 loaded at 1.5 to a Katana 97 and though the Katana is truly more ground hungry, I immediately felt safer with its longer recovery arch, giving me more time to go for rear risers, adjust the direction if necessary, etc. I had been warned of this fact before jumping it and I just started the turns higher and went down little by little, with patience and getting mentally accustomed to the loss of altitude in the turn. I did not have the feeling at any time that I suddenly had got into an absolutely new race machine that wanted to kill me at the first possible occasion or anything like that. I felt very comfortable from the beginning.
I am not saying that this change is the most recommendable, but it is not something crazy having a little of patience and care.
The Katana (of course smaller) is definitely more sensitive to body position on opening, but once this is taken care of, it opens fantastically.
