I find this match-up rather odd as well. Maybe it's my opponents or my odd play style but I often find that playing defensive against an aggressive Jin works fine. Oddly enough the Jins I faced would never expect me to throw aerial ice swords as they rushed in on me whether they were rushing in on the ground or mid-air. I would also just distance myself and play Jin in a manner similar to Ryu in ST but with combos of course (which I fail at doing half the time) lol. I'm still a beginner at BB so I guess something weird like this may work out for me for now but what do you guys think? Also besides 5D, I find ice swords are also good at stopping ground ice cars.
