Also, I feel his normal attacks could use some more clarification and details on usage in certain situations. If anyone wants to help with that, feel free.
Well, here's something short and simple. Could use some adding to or editing. I only covered Anti-Air and Air-to-Air.
Anti-Air:
st.A: Terry's best choice for dealing with hops. Very quick recovery. Not effective for jumps.
df.C: Terry's best choice for dealing with jumps. Works for hops, but st.A is a better choice and has less recovery on whiff. (Notes: Often trades in Counter Hit situations. If the opponent's move does not lead to a hard or soft knockdown, can combo into Buster Wolf. Against some moves, it makes for a poor anti-air. Ex: Kyo j.2C)
Far st.C: This makes a good alternative to st.A for anti-airing max range range hops / hyper hops. It has more reach.
Air-to-Air:
j.B: Terry's quickest move for Air-to-Air. Good horizontal reach. Use it to cover space in the air, whether you're going neutral, forward, or back. Ineffective for Air-to-Ground.
j.CD: Another great Air-to-Air that keeps Terry covered when he hops or jumps. Terry's j.CD is very swift, but has exactly twice the startup of j.B; Use accordingly. Can lead to Counterhit combos with Crackshoot. Ineffective for Air-to-Ground.
j.D: This is less of an Air-to-Air move and much better for Air-to-Ground, but if you are in a higher jump arc than your opponent, j.D can be a good choice.
j.C: This is the perfect medium in the air. Not as much horizontal reach as j.B, and is 2 frames slower. j.C can be used for both Air-to-Air and Air-to-Ground. If you are unsure which normal to throw out in a specific hop / jump, j.C is a good choice.

As for combos, I was thinking something along the lines of 3 different lists for HD.
One for 0-2 bar stuff that covers all parts of the screen.
Another for 3-5 bar combos that make the most out of HD and cover the entire screen. ( Max cancels, Strict Spacing, but easy execution)
Another for 3-5 bar combos that don't have such strict spacing and also covers the entire screen.
Quick combo list could use some editing imo.
