Depending on if your opponent has meter or not, your best bet may be to block and see what he does as he may be in desparation mode to use an enhanced move, use X-ray himself, or wait for you to straight missile (an obvious choice for Sektor due to the distance the X-ray creates) so he can punish. Chances are, if you've landed an X-ray, he may want to close distance because he is behind. If so, and he is a teleporter, look for that and block. If he is not, then he may close distance by jumping in, in which case up missile front is your best bet.well lets say if i didnt you my x-ray to end the round?
Fighting games are situational. I can't give you the best move to try after X-ray, only what could be a good course of action depending on the examples. Try to refrain from using X-ray with Sektor - A full meter is a bad sign for a Sektor player.
