I found 2 staple and reliable HD combos starting from a jump-in or a low by spending 2 meters... This works from full screen...
j.D, s.C, f+B, HD, s.C, f+B, [qcf+A, DC, dp+C~A+B, TK hcf+B] x4, Neomax = 854 dmg
cr.B, s.B, f+A *3 hits*, HD, s.C, f+B, [qcf+A, DC, dp+C~A+B, TK hcf+B] x4, Neomax = 739 dmg
If you are in the corner then you can just replace the TK hcf+B with qcf+A for the same damage and make the combo easier to do...
For a 1 meter HD combo He still gets amazing damage...
j.D, s.C, f+B, HD, s.C, [qcf+A, DC, dp+C~A+B, TK hcf+B] x5, qcf~hcb+A = 803 dmg
cr.B, s.B, f+A *3 hits*, HD, s.C, [qcf+A, DC, dp+C~A+B, TK hcf+B] x5, qcf~hcb+A = 687 dmg
