I'm going to go against the grain and urge you NOT to get Control. Pulse stops are never meant to be taken lightly, and if you only want to learn one to "be the guy who gets the best reactions," then to be perfectly frank you don't deserve to perform it. Think about this. The spectators literally see and feel you die. One girl I performed this for was practically in tears because she thought she'd done something wrong and almost killed me. I don't trust such an effect in the hands of someone who doesn't appreciate the emotional resonance. Jesus, am I the only one here who thinks this?
