Back to messing around with Donnie. Took a look at his b1 after db2. I'm not the biggest fan of giving up combo damage for 13 so I'm trying to work around it. What I found is you should basically be using b1 as a conditioning tool on their wakeup after db2, and it has a few interesting properties. First, if you don't do it early enough, the b1 will whiff. Second, if done correctly, it will hit the opponent and force them to block/stand closer to Donnie than they would have if they just got up naturally. Also, with the correct spacing you can either hit in front or cross up. Lastly, while it can beat out some wakeups, you can definitely be punished easily, hence the conditioning.
Once you've trained them to block low on their wakeup, that's when you can start going for the crossup bombshells off of b1. Check it out.
And then I just included a little sequence to show off what's possible with perfect reads and some meter.
