The meter-less BnB off B21:
B21xTrident, JiP, S4xSmoke Bomb, NjP, S4, F43xTP
Does 31% but leaves you with no real advantage.
Changing it to this BnB here:
B21xTrident, JiP, S4xSmoke Bomb, NjP, S4xPhase, 21, F131
Is pretty easy, does the same damage, corner carries them further, leaves you with an advantage (even if they roll), builds you more meter, and actually gives them less meter during the combo, and it leaves you with options.
You can use
@GinTonicTrain 's far Smoke Bomb tech to immediately Oki on wake up if they roll, you can cancel into a second phase back or forward for immediate respoisitioning and still be plus enough to beat all (non-armoured) wake ups even after a roll, or you can cancel into a safe ex Invis set-up, or just do nothing and take your advantage depending on screen position.
Obviously this applies to all combos that start with a standing spear. Up to you guys, but it's what I'm going to be using.
