Couple of things I noticed in the corner. You can get a full combo from his regular second shoot. Here's the break down.
d.B x2, qcf+A, f+B qcf hcb+AC (EX Chain Drive) - 385 dmg
d.B x2, qcf+A, f+B, ~delay~, st.A, qcf hcb+AC - 399 dmg
d.B x2, qcf+A, f+B, ~delay~, st.B, qcf hcb+AC - 403 dmg
So for 2 stock, you can do 40 percent off an easy hit confirm. I was trying to figure out a way to TK an EX Air Minute spike off an Ein Trigger, Second Shoot chain, but either my execution is pretty bad or it's not possible. I thought I'd done it, but I might have just popped them up really high. You could do air minute spike after the st.A though which can be followed into an Air Minute spike so that might be interesting too.
EDIT:
The next big thing I wanna focus on is his new hit confirm with st.C, f+A. In order to get a decent combo off of that one, you have to do qcb+D x2 really fast to make the slide come out and combo. After, you can do st. A into TKed Air Minute spike..
