Right now, both the 104J and 104G are 10.0 in grb. The 104J is literally the same plane as the 104G, except it has the ordinance hardpoints removed and is incapable of carrying bombs. Considering how useful bombs are for a fighter in grb, the 104J ought to be at most 9.7, which would also let it fit well in ground lineups, as Japan has a huge gap feom 9.7 to 11.7
