Okay, so you're basically between a rock and a hard place here. You have to know I'm just gonna stall this round to blow through your Endure and there's not a ton you can do to prevent that...that said, the most potent weapon of someone looking to stall out a round is suspended D/E moves. You're only using two subs; I would have a sub saying to replace Endure with Haze if I use some amount of suspended D/E moves.
