I can give some advice, I used to play Vega and now I’m a T.Hawk main. Vega outpokes T.Hawk and many times you’ll stuff his pokes, and so the best strategy is to keep him out with them. If you’re able to get a KD on him, cross him up with the FBA and then use the Izuna Drop. T.Hawk is really free against this because his only reversal option is to use the Tomahawk Buster (DP), which has a slow startup and lacks decent hitbox range, and so there’s a very good likelihood that if the T.Hawk Player we’re to reversal with it that they’ll whiff it and you’ll catch them with the Izuna Drop in the end. T.Hawk has a difficult time competing with Vega on a grounded game, and If you’re able to keep a T.Hawk out effectively with pokes, I guarantee that at one point or another the T.Hawk will resort to jumping as a way to get in. Vega also takes priority over T.Hawk in air-to-air as well, and the Neutral Jump HK works pretty well. Hope this is helpful.
