Hm, in counter formations it is also said that counter for Hex is 343 (I guess it's 3N=3DC defence). What I wouldn't use for sure is 451V and 4141. Maybe you should use normal mentality classic 442 with red arrows on ML and MR, short/mixed passing through flanks, zonal marking, low pressure. If you would have to attack him, then just switch mentality to attack and try use offside trap, which usually is useful against 3ST (even more if oppo uses red arrows on them). Good luck!
