Zap Cannon is indeed a bit too risky, of course, but if it connects, then there's always the chance of PARing the opponent. And since I would have no T-Wave for backup...

Additionally, since the main focus of the second set is for BPing, I would only utilize ZC as a last resort if the situation becomes unfavorable on my part. If dilemma goes south, I'd take the gamble to damage and PAR the opponent in one attack, like mentioned.
